SPECTRUM SCRAMBLE RECEPTION SYSTEM

摘要

PURPOSE:To minimize noises of audible level by making a noise spectrum of an output of an FM reception means flat to prevent the noise spectrum from being affected with spectrum scramble. CONSTITUTION:A signal received by a reception antenna 21 is demodulated by an FM demodulation section 22 and outputted from an output terminal 25 via a spectrum descramble section 23 and an integration device 24. The FM demodulation section 22, the spectrum descramble section 23 and the integra tion device 24 are connected in cascade to constitute a processing function, and the descramble section 23 applies spectrum descramble to a demodulation output signal of the FM demodulation section 22 and the descrambled output is integrated by the integration device 24 and a received output is led out.
