Patent JP-H025268-A (JP)
Title: Signal omission correcting device
Inventor: ONUKI NOBUTAKA
IPC: G11B20/10
Filed: 1988-06-24
Abstract: PURPOSE:To ensure the output of a faithful correction signal in place of a reproduction signal by differentiating and holding the reproduction signal and taking out and integrating the immediately preceding differentiated value of the reproduction signal at omission of the reproduction signal. CONSTITUTION:The input reproducing signal is outputted via a contact B and a switch 8 and at the same time the high frequency band noises of the reproduction signal are eliminated by an LPF 1. Then the input signal is amplified by a buffer amplifier 2 and differentiated by a differentiating circuit 3. This differentiated signal is inputted to a holding circuit 4 via a switch 5 and held as the voltage value. If the omission of signals are produced, both switches 5 and 8 are switched with interlocking by the detection output. As a result, the differentiation value obtained immediately before the signal omission and held by the circuit 4 is inputted to an integration circuit 7 via an amplifier 6 for conversion of impedance. The result of integration is outputted via a contact A and the switch 8 as a correction signal substituting the reproduction signal. Thus it is possible to hold the tilt of a signal waveform obtained right before the signal omission and to obtain a signal that corrected faithfully the omitted reproduction signal.
