Title: Frequency modulation audio signal processing circuit
Inventor: UENO MASASHI
IPC: H04N9/802
Filed: 1989-07-25
Abstract: PURPOSE:To effectively reduce noise component distributed over a high frequency band by varying a time constant T2 in two time constants T1, T2 (T1>=T2) specifying the high frequency emphasis characteristic in a range of T1>=T2>=T3 in response to the signal level after weighting an audio signal of a higher frequency than f1=1/2piT1 by means of the high frequency emphasis characteristic having a weighting means. CONSTITUTION:An input audio signal to an emphasis circuit 3 is fed also to an amplifier 13, amplified by a prescribed gain, and only an audio signal of a higher frequency band than f1=1/2piT1(Hz) is extracted by a high pass filter 14 and fed to a weighting circuit 15. The high frequency emphasis characteristic is given to increase f3=1/2piT2(Hz) to the weighting circuit 15 by controlling the gm as the signal frequency gets higher. High frequency noise components are reduced by combining emphasis-de-emphasis operations in this way.

Title: Demodulating circuit
Inventor: OGAWA ATSUSHI
IPC: H04H40/36
Filed: 1982-11-02
Abstract: PURPOSE:To hold a detection output and to prevent the generation of a noise in case of AM overmodulation through simple constitution by extracting a frequency component from a demodulated signal which contains signal information on an amplitude and a frequency component, and extracting an envelope from the signal and detecting it as being less than a specific value. CONSTITUTION:The demodulated signal which has signal information on the amplitude and frequency components is demodulated to obtain respective information signals corresponding to respective amplitude and frequency components. For this purpose, a signal from an IF signal source 11 is applied to a limiter amplifier 15 to extract the frequency component. A peak detecting circuit 19 extracts an envelope component from the output signal of a circuit 12 and the 1st comparing circuit 20 compares the component with a reference potential and sends the result to an OR circuit 21. Further, signals (L-R) and -(L-R) are applied from a quad latch detecting circuit 16 to a smaple holding circuit 23 by the output of an amplifier 15. When the output of the circuit 21 is lower than the specific value, the output of the circuit 16 is applied to a matrix circuit 14 and when higher, it is held by the circuit 23, thereby preventing noise generation in case of AM overmodulation.
