    摘要： There is provided a detection circuit for TV receiver which includes a frame comb filter and a field comb filter and which generates a luminance signal or a chrominance signal by effecting addition or subtraction upon video signals of two frames adjoining each other included in the received TV signal. This detection circuit includes a synchronization separation circuit, an APC circuit, a frequency division circuit connected to the APC circuit, and a comparator circuit connected to the frequency division circuit. The frequency of the chrominance subcarrier signal is demultiplied by the frequency division circuit. The phase of the chrominance subcarrier signal thus frequency-divided is compared with the phase of the synchronizing signal separated by the synchronizing separation circuit. It is thus judged whether the received TV signal is a standard TV signal or a nonstandard TV signal.

    摘要： A digital television receiver includes a decision circuit for deciding whether an input television signal is a standard signal or a nonstandard signal. A first clock signal generator circuit for generating a first sampling clock signal synchronized with a color burst signal is provided in combination with a second clock signal generator circuit for generating a second sampling clock signal synchronized with a horizontal synchronizing signal. When the standard television signal is received, the television signal is processed by employing the first sampling clock signal. When the nonstandard television signal is received, the television signal is processed by employing the second sampling clock signal.

    摘要： An electron emission type display apparatus has on a flat plane a matrix layout of multiple light-emitting elements which are connected to cross-points of longitudinal and lateral common electrodes, for sequentially turning on a line of light-emitting elements connected to a common electrode. In such the device, distortion takes place in drive waveform since a low-pass filter (LPF) is formed by a combination of the wiring resistance of the common electrode and the capacitance of a light-emitting element. To avoid such waveform distortion, the width of a light-emitting element driving voltage pulse is caused to be greater than the width of a scan voltage pulse.
