Abstract
PURPOSE: To make it possible to test and adjust easily a waveform compensator circuit by superposing and sending a false random signal for a receiver adjustment in nearly the entire scanning period of a TV signal.
CONSTITUTION: On the basis of a signal from synchronization board 1, clock generating circuit 2 generates a clock signal in phase at every H synchronizing with chrominance subcarrier (fsc). On the basis of a signal from synchronous board 1, line counter 3 generates a count output for false random PN signal generation. Further, a character signal generating circuit generates a character signal. On the other hand, PN signal generating circuit 5 generates a PN signal on the basis of the clock signal of circuit 2. In addition, video signal generating circuit 6 generates a composite video signal. Then, synthesizer circuit 7 superposes signal X in a vertical blanking interval and inserts the PN signal at the same position in each horizontal scanning interval at part of each initial point during a horizontal scanning interval from, e.g. 22∼262H-th horizontal scanning interval. This display test signal is supplied to RF modulation circuit 9, where a RF carrier of any channel is modulated and sent out.
