Title: Pulse noise reduction circuit
Inventor: HANAI AKIHIKO
IPC: H03H7/01
Filed: 1987-04-16
Abstract: PURPOSE:To obtain a pulse noise reduction circuit having a large ratio in digital IC adoption by providing a trigger circuit section including a prescribed sample hold circuit in place or a high-order active high-pass filter. CONSTITUTION:When an input voltage Vc is inputted to each input terminal of a transmission circuit section 1 and a trigger circuit section 2 in a pulse noise reduction circuit, a sample hold circuit 6 samples an input voltage Vi including a noise pulse P at a period of, e.g., 5mus and holds the sampling voltage Vs till the next period. Thus, the leading of a first pulse P1 included in the voltage Vs is retarded by a time tau. Then voltages Vi and Vs are subtracted in a differential amplifier A2 and a waveform including a pulse P2 having a pulse width tau1 with the same leading as the pulse P is obtained as the output. Then the rectified output Vr is obtained through a full wave rectifier circuit 7 in response to both bipolar properties of the pulse P. Denoting the reference voltage of the comparator circuit 8 as Es, then the trigger pulse Vt synchronously with the pulse P2 is obtained and an output voltage V0 is obtained.

Abstract: PURPOSE:To suppress the low-frequency resonance of any cartridge equally by controlling the gain of a feedback system in accordance with the sensitivity of the cartridge. CONSTITUTION:A low-frequency resonance frequency accompanying the turning of record 8 is detected by cartridge 12 and this detection output is amplified by AC amplifier 4 by way of LPF3; and the output of amplifier 4 is supplied to driver 5 through gain change-over unit 14 to drive electromagnet 10, and consequently suction force and repulsive force are generated between the electromagnet and permanent magnet 9 to damp tone arm 1, thereby suppressing low-frequency resonance.
