Title: Noise reduction circuit
Inventor: KAWATAKE MASATOSHI
IPC: G11B3/00
Filed: 1995-05-24
Abstract: PURPOSE: To eliminate only noise even when a signal including consecutive pulsive voice signals is inputted by providing a noise discriminating circuit. CONSTITUTION: A discrimination signal NS indicating the presence of a pulsive signal is obtained by extracting the component B of the high frequency range signal including the pulsive signal from a voice signal A by a high frequency filter 2 and by passing it through a signal ratio comparing circuit 5. Next, the switch 12 of a single-shot noise discriminating circuit 10 closes a contact in accordance with the discrimination signal NS to transmit the reference voltage VR from a reference voltage source 11 to a release filter 13 only for the period of the pulse width of the signal NS. Moreover, a delay circuit 14 delays the release signal F by a prescribed fixed time to generate a delayed release signal G.  When the level of the signal F is sufficiently smaller than that of the signal G, a discrimination circuit 15 discriminates the signal as a voice signal and transmits a discrimination signal MN to an amplitude judging circuit 6. Thus, the circuit 6 judges the signal as the voice signal when plural pulsive signals are generated in a fixed time and judges the signal as a pulsive noise signal when the pulsive signal is generated singly in that time.
