  • Satellite Broadcasting?

    Now that the first demonstrations of satellite-relayed transoceanic television may occur within two years, what is the probable future of satellite broadcasting? This study examines problems of broadcasting via satellites directly to home television receivers, compared with those of relaying to earth-terminals and rebroadcasting locally. The former eventually may be possible, but would require high-power, highly engineered satellites and would involve other problems, which are discussed here. Direct FM audio broadcasting may be less difficult but also less spectacular and rewarding. View full abstract»

  • A Complete Specification of the Gain Control Characteristics of RF And IF Transistors

    Publication Year: 1961 , Page(s): 23 - 28

    This paper describes a unique method for specifying the gain control characteristics of high frequency transistors over their entire AGC range. The forward gain control characteristics of transistors can be measured by means of a curve tracer to permit the specification, within published limits, of the high frequency power gain versus collector to emitter voltage curve. While this report describes the specification of forward gain control characteristics the system can also be used for reverse gain control specifications. View full abstract»

  • A New Compact VHF TV Tuner

    Publication Year: 1961 , Page(s): 29 - 34
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3031 KB)  

    A brief review of the performance requirements and other factors influencing the design of VHF television tuners is presented, including some of the unforeseen problems encountered during development of a new design. The basic electrical similarity between tuners of different manufacturers is pointed out, which suggests that significant design improvement might best be obtained by concentrating attention on mechanical rather than electrical factors. Development of a new compact tuner was begun with maximum use of molded plastic parts, reduction of the number of mechanical parts, and suitability for automatic production techniques as the main design objectives. A final design was completed and the tuner is now in production. A description of the novel features of this tuner indicates how the design objectives were reached and greater product uniformity and lower costs realized. View full abstract»

  • An Efficient Noise Immune Sync and AGC Circuit for Television Receivers

    Publication Year: 1961 , Page(s): 35 - 38
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1594 KB)  

    Impulse noise interference, such as may be caused by sparking electric motors or automobile ignition systems, can interfere with the performance of a television receiver in the following principal ways: First, the impulses appear directly in the picture; second, the synchronization separator input circuit may charge up to such an extent that the picture loses synchronization; third, the impulses may provide false information to the AGC system thereby causing a sharp reduction receiver gain. Of the three, the latter two effects are by far the more serious. Consequently, noise ``suicide'' or noise inverter circuits, for the protection of the sync separator and AGC circuits have been widely used. View full abstract»

  • A Precision-Tuned Receiver Employing Solid-State Tuning Elements

    The capability of rapid frequency selection coupled with crystal controlled tuning accuracy are the salient features of this solid-state receiver. The heart of the system is a discrete local oscillator. It consists of an electronically tuned oscillator which is phase-locked to a selected harmonic of a master crystal. Since there are no mechanical adjustments necessary, the receiver can be built in a small, light-weight package. View full abstract»

  • A Solid State Oscilloscope Display

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2375 KB)  

    A new solid-state display device utilizing certain unique properties of piezoelectric and electroluminescent materials is described and the principles of operation are reviewed. The device requires only four properly timed electrical inputs to produce a spot of light at any selected point on the display panel. The timing relationships are derived and a system capable of producing the required drive signals is described. Oscilloscope patterns are generated on the panel by a point-by-point plot of suitably processed X-and Y-input signals. View full abstract»

  • Factors Affecting Overall Performance of FM Stereophonic Receivers

    A flat phase linear IF pass band should be designed into a high fidelity stereo tuner. A vector analysis of a tuner exhibiting an equivalent 5 usec. deemphasis in its output voltage vs. frequency characteristics shows that the major cause of poor stereo performance is related to the level differences of the L + R and L - R channels. A simple adjustment of the L + R level control in the synchronous oscillator stereophonic adapter circuit described can correct this difference. View full abstract»

  • Design of Stereophonic Receiver for a Stereo System in the FM Band using an AM Subcarrier

    From the FM discriminator in the receiver we derive the composite signal containing a low frequency audio signal, a modulated subcarrier and a pilot signal related to the subcarrier. The stereophonic signal demodulator can operate on the composite signal in such fashion as to produce directly a left and right stereophonic signal. View full abstract»

  • Stereophonic FM Broadcasting

    In arriving at a suitable choice of transmission parameters for stereophonic FM broadcasting, consideration must be given to several factors, as follows: 1. The modulation choice should provide an aurally-balanced program for the monophonic listener. 2. A reasonable compromise should be made between the stereophonic signal-to-noise ratio and the monophonic signal-to-noise ratio as compared to monophonic broadcasting. 3. Receivers designed for the system should be capable of reliable operation yet should be reasonably inexpensive. 4. If possible, the system should provide an additional channel for other services without degrading the desired service. View full abstract»

  • An Ultra-Low-Distortion Transistorized Power Amplifier

    The development of a new type of power transistor has made possible the construction of ultra-high-performance audio-frequency amplifiers which can equal the performance of the finest vacuum-tube amplifiers available. The design, construction, and performance characteristics of such an amplifier, using RCA drift-field power transistors, is discussed. The amplifier is capable of providing a power output of 50 watts at less than one-half per cent distortion from 20 cycles to 20,000 cycles. Also discussed are a five-watt class A amplifier and a 15-watt-per-channel stereo amplifier which combine high performance with economy. View full abstract»
