  • Computer Aided Design of Horizontal Deflection Systems

    The design of horizontal deflection systems is usually determined empirically by experienced electronic engineers. The use of equations and formulas is, in general, unsatisfactory. They require many hours to solve and the results are, at best, only approximate. View full abstract»

  • Low Cost Voltage Regulator for Varactor Tuned Auto Radio

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1765 KB)  

    Electronic tuning for AM radios becomes possible with today's varactor diodes. The large capacitance values available permit smaller AM radios and remote tuning. Utilization of varactor diode tuning, however, demands extreme voltage stability, since small changes in the tuner reference voltage will change the diode capacitance and therefore the resonant frequency.

  • Investigation of Microstrip Applications for Varactor-Tuned UHF Tuners

    The use of microstrip with varactor diodes to construct a UHF tuner for commercial television receivers is a marked departure from previous exploitations of microstrip. Usually, it has been used for network elements in broadband applications with fixed center frequency. Such applications are diametrically opposed to the conditions in UHF receivers, where fractional bandwidths less than 5% are required over nearly an octave variation of center frequency. The scope of this paper is a discussion of the most fundamental problems associated with microstrip in varactor-tuned UHF tuners. These problems are as follows: 1. Determination of parametric relationships 2. Delineation of device limitations 3. Formation of an approach to preselection View full abstract»

  • A Comparison of Solid State Sub-Carrier Oscillators for Color TV Receivers

    Page(s): 37 - 42
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1625 KB)  

    Increasing use of semiconductors in color TV circuitry has permitted the evolution of many different methods for color sub-carrier regeneration. This chassis function is a major contributor to color picture quality since phase errors introduced in the regeneration process can result in tint errors easily discernible by the most unskilled viewer. The solid state circuits commonly used or recommended for use in this area may be classified by operating principles as follows: 1) Automatic phase control (APC) loops 2) Injection locked oscillators 3) Crystal ringing circuits.

  • A Transistorized Fifth Harmonically Tuned Horizontal-Deflection Circuit for Large-Screen Color TV

    One of the problems associated with horizontal deflection and high voltage systems utilizing third harmonic tuning of the flyback transformer for large screen color TV (25¿-90°tubes) has been the high voltage regulation. In tube sets, the shunt regulator has been widely used; and, more recently, a feedback scheme to the horizontal output tube has been used to achieve better regulation. However, the shunt regulator has proved undesirable because of reliability, and it is a potential source of X-rays. The feedback scheme does not lend itself to transistor circuitry because the horizontal transistor is operated as a switch. Therefore, in making a transition to transistor horizontal deflection and high voltage systems, regulation becomes a problem. View full abstract»

  • Intermodulation and Cross Modulation as a Function of Mixer Pinch-Off Viktage in an FET FM Receiver

    The superheterodyne receiver was first described in 1919,1 and in a discussion of choice of intermediate frequency which acompanied that description the possibility of multiple responses was first suggested.2 Thus, the receiver spurious response has reached its golden anniversary, and like many an old timer it provokes disinterest if not outright boredom. In spite of the variety of transistors and other devices newly available to designers in the past decade, no documented improvement in receiver spurious response performance has been achieved. Apparently it is assumed that there is an adequate knowledge of the mechanisms of spurious responses, methods for the measurement of same and design techniques for their reduction. The results presented here indicate that much design improvement is possible, for it was found that the cross modulation performance of a production FM tuner could be improved by 50 dB simply by replacing the mixer transistor with another having different characteristics.

    Proposals for home color television receivers which would provide for more than just the display of broadcast programs usually have centered around the inclusion of a color video tape recording system. A comparison of closed circuit television systems for conventional color film with systems for color video tape recording suggests greater potential for film systems. View full abstract»

    Portable, transistorized television receivers are usually designed to operate from 12 volts DC. The converter for AC power line operation in most TV sets is built in, but in a few sets it may be in a small box at the AC prong end of the line cord. A cigarette lighter plug in cord accessory is usually supplied for operating the set from an external 12 volt battery as is found in most automobiles, boats, private airplanes, etc. View full abstract»
