    A method of analyzing common-emitter transistor video amplifiers has been given that is sufficiently simple and accurate for design work. This paper discusses the use of the above design method for the purpose of obtaining RC-coupled stagger-tuned video amplifiers. For a poles-canceling-zeros scheme, the design equations are given relating external circuit parameters to desired response shape and transistor parameters. By means of stagger tuning, the gain-times-bandwidth factor of a transistor amplifier is kept at unity as in the case of stagger-tuned vacuum tube amplifiers. Experimental results are given for amplifiers that are designed to be maximally flat by this method. View full abstract»

    The behavior of local oscillator tubes and associated circuit elements under the complex conditions of heat flow can be treated analytically. By means of such an analytical treatment, local oscillators at frequencies up to and beyond 1000 mc may be stabilized methodically with conventional temperature-sensitive elements. The resultant frequency stability is generally satisfactory for most practical purposes. View full abstract»

    A simple, efficient cathode-ray tube deflection circuit suitable for standard television horizontal sweep applications with excellent linearity has been developed. The circuit employs either a single transistor or a tube, operated as a switch. The sweep amplitude may be adjusted continuously without affecting the linearity or general performance of the circuit. The switching operation is such that the inrush current upon closing the switch and the voltage build-up upon opening the switch are delayed sufficiently to prevent excessive momentary dissipation in the switching device. This and other circuit characteristics makes it possible to operate the switching device efficiently, particularly when the circuit is transistorized, and therefore permits exceptionally wide deflection angles with a relatively small transistor.

    A solution is sought to the following problem: Given a wide bandwidth of the order of 50 kc, devise standards such that the entertainment value shall be maximized. Four applications are considered: tape recording at a tape speed of 15 inches per second; telephone conversation accompaniment over high-quality telephone lines; long-distance wire-line transmission over high quality telephone lines; and short-wave transmission over a 120 kc channel. Bandwidth reduction is achieved through reduced resolution, reduced field frequency, increased interlacing ratio, the use of dot interlace, and the use of quantizating and coding. The scanning frequencies and synchronizing signal are derived for each case. In addition, for the short-wave system, a method of combating multipath transmission is suggested. View full abstract»
