    摘要： In a channel selecting apparatus for a television receiver having a tuner with a voltage-controlled, variablereactance device as its tuning element, and in which such tuning element has a non-linear relation between its control voltage and the resulting receiving frequency; a sweep pulse generator is operable for producing sweep pulses, a counter counts the sweep pulses for producing progressively changing binary codes corresponding to the changing counts of the counter and which represent respective control voltages for the variable reactance device, a digital-to-analog converter receives the binary codes and converts the same into the respective control voltages for the variable reactance device, and a circuit is provided for varying the period of the sweep pulses so that the rate of change of the receiving frequency is substantially uniform over the range of the progressively changing binary codes. Such circuit for varying the period of the sweep pulses is preferably operable by the binary codes so as to respond to the changes in the latter.

    摘要： An AFT circuit for a television receiver automatically adjusts the frequency of a tuner local oscillator, not only on the basis of an error signal provided from an AFT discriminator, but also on the basis of horizontal synchronizing pulses contained in the video signal to which the receiver is tuned. A synch signal detector detects the presence or absence of the synchronizing pulses. A control circuit provides a control signal to the local oscillator in response to the AFT error signal when the latter is above or below a reference voltage such that the desired frequency is within an AFT capture range. However, when the AFT signal is at the reference voltage, the control circuit provides the control signal based on the presence or absence of the synchronizing pulses, such that when the pulses are present, the local oscillator frequency is raised, but when the pulses are absent, the local oscillator frequency is lowered. Then, when the AFT signal is present, the local oscillator is controlled thereby. This AFT circuit has an expanded effective capture range, and is prevented from locking onto the sound carrier of an adjacent channel. 00202

    摘要： Digital data transfer in a digital television receiver between an internal central processing unit, or an external computer, and the video/audio processing circuitry by way of an internal bus is accomplished efficiently and without producing noise interference by using a high-frequency clock signal and a relatively low-frequency clock signal at different times. The high-frequency signal would normally produce visually perceptable noise, however, it is employed only during vertical blanking intervals, and the low-frequency clock signal, which would not produce visually perceptable noise, is used at all times other than the vertical blanking intervals, whereby noise interference that would be otherwise seen on the visual display of the television receiver is suppressed.
