IPC: H03H11/04
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To perform automatic adjustment on an IC so that a signal processing circuit has a desired frequency characteristics. SOLUTION: An analog filter 12 having the same frequency characteristics as an analog filter 11 is formed on the same IC chip as the analog filter 11 which has the desired frequency characteristics and actually performs filtering processing of an input signal Vin. A reference signal Vref whose frequency corresponds to the characteristics frequency which determines the frequency characteristics of the analog filter 11 is inputted to the analog filter 12. A low pass output V 1 and a trap output V 2 outputted from the analog filter 12 are multiplied by a multiplier 13, and a multiplication output V 0 passes a low pass filter 14 to detect an error signal Ve, and characteristics frequencies of analog filters 11 and 12 are controlled based on this error signal Ve.

Title: Method of measuring pulse frequency
Inventor: KOJIMA HIROSHI
IPC: G01R23/10
Filed: 1989-08-30
Abstract: PURPOSE:To measure the transient lowering of frequency in extremely low frequency by setting constant cycle timing having a cycle longer than that of a clock pulse. CONSTITUTION:When the number of clock pulses contained between the pulses of input pulses is counted, the cycle of the input pulses is operated and fre quency is operated as the reciprocal of said cycle. Herein, constant cycle timing is set at the continuous point of time having a constant cycle longer than that of the clock pulses and a certain input pulse is set to the first input pulse and the point of time thereof is set to ti1 and the cycle of the point of time is set to TL. When a time TL is elapsed without the input of the second input pulse after the point of time ti1, the cycle on and after this point of time becomes larger than the cycle TL and frequency is lowered. When the point of time tt of the constant cycle timing comes thereafter, a time Ti=tt-ti1 becomes near to the cycle of an actual input pulse rather than the cycle TL and, by setting the cycle TL to the cycle at the point of time tt, a measured value near to actual frequency can be obtained before the next pulse is inputted.
