<p>PURPOSE:To provide the waveform equalizing device whose waveform equalization time is not influenced by a processing speed of a CPU in a waveform equalizing device for correcting a waveform distortion generated in the transmission path at the time of transmitting a television signal. CONSTITUTION:The device is constituted of an adder 6 for setting a reference signal superposed on a television signal as one input, a delay element 5 for delaying an output signal of the adder 6 and setting it as the other input of the adder 6, an ideal reference signal generating part 8 for generating an ideal waveform of the reference signal, a substracter 7 for executing subtraction of the ideal waveform of the reference signal generated by the ideal reference signal generating part 8 and the output of the adder 6, a waveform memory 4 for fetching an output of the subtracter 7, a CPU 3 for executing a waveform equalization arithmetic processing by using the reference signal fetched to the waveform memory 4, and a transversal filter 2 which can execute write of a coefficient by the control from the CPU 3.</p> |
