Title: Correcting device of frequency characteristic
Inventor: NISHIKAWA KAZUNORI
IPC: G11B20/00
Filed: 1982-08-18
Abstract: PURPOSE:To correct the frequency characteristics, by dividing a digital signal or a wave signal to be modulated into high and low frequency bands and obtaining a fixed level ratio of output signal levels through two BPFs to add and mix these output signals with control of their levels. CONSTITUTION:The frequency band of a wave signal to be modulated which is reproduced from a disk is divided into two parts through an HPF2 and an LPF3 and at the same time supplied to BPFs 4 and 5 to be sent to detecting circuits 8 and 9 respectively for detection of envelope curves. These signals are converted into DC signals to undergo comparison and control of levels through a level controller 10 and then supplied to a comparator 11. The comparator 11 delivers a control signal to vary the gain of a variable gain circuit 6 in response to the difference levels of two input detecting signals if any. The control signal is added and mixed with a low frequency component through an adder circuit 7. Thus a reproduced wave signal to be modulated which has the compensated attenuation of a high frequency component is delivered to an output terminal.
