PURPOSE:To use storage information to eliminate distorted signal components from a real signal, by storing a signal for distortion compensation to a rewritable non-volatile memory after converting the signal into a digital signal, and picking up the storage information after converting into an analog signal as required. CONSTITUTION:Waveform data to an input terminal 3 of a waveform storage generating circuit are formed by converting a waveform signal at an AD converter (not shown) and the waveform data are transferred to the non-volatile memory 1 or a DA converter 5 at a switching circuit 4. Thus, the memory 1 stores the waveform data via the switching circuit 4 semi-permanently, the data is given to the DA converter 5 through the circuit 4 with a control signal to a control terminal 2, and a prescribed waveform analog signal is generated from the DA converter 5. This waveform storage generating circuit is used, for instance, for a signal circuit for distortion compensation of a video camera. |
