Title: Adaptive high pass filter
Inventor: MIKI TSUTOMU
IPC: H03H11/04
Filed: 1989-02-15
Abstract: PURPOSE:To control the cut-off frequency adaptively in response to the signal component with a low frequency included in an input audio signal by providing a control means controlling the cut-off frequency in response to the power of a signal component with a low frequency included in the input audio signal. CONSTITUTION:A subtractor 16 outputs a signal representing a low frequency power of an audio input signal Vi and gives it to an integration device 17. The integration device 17 smoothes a given signal and gives a smoothed signal to a VCO 18. The VCO 18 generates a clock signal in response to a signal given from the integration device 17. The cut-off frequency as a high pass filter of a switched capacitor filter (SCF) 11 is varied proportional to the frequency of the clock signal phi supplied from a frequency divider 19. When the power of the low frequency signal component included in an input signal is high, the cut-off frequency of the SCF 11 is increased and the low frequency component signal of the input signal Vi is suppressed, When the power of the low frequency signal component of the input signal Vi is suppressed, the cut-off frequency is decreased and the low frequency signal component passing through the SCF 11 is increased.

Title: Holding circuit of maximum and minimum
Inventor: SUGA YUUJI
IPC: G11C27/00
Filed: 1983-03-04
Abstract: PURPOSE:To sample the maximum and minimum in a signal without increasing a sampling rate by operating a peak holding circuit only at a signal part with steep level variation and holding its output for some period. CONSTITUTION:The frequency of a band-pass filter 7 is set almost to a sampling frequency f0. An extraction signal T1 is received and outputs T2 and T3 of slicing circuits 8 and 9 are turned on in periods T1>=VH and T1<=VL to turn off current switches 11 and 12. When an input signal contains a component of frequency f0, T1 corresponding to its increase or decrease is generated, and when it increases, the T2 is turned on to cut off the current switch 11, stopping the discharging operation of a holding capacitor. At this time, the T2 is outputted DELTAtD behind the T1, so the T2 is on for a period DELTAt after the peak of the input signal. Simultaneously, the peak holding circuit 10 detects and holds the peak and the capacitor is discharged up to Vi once the T2 is turned off again and operates thereafter following up Vi.
