Title: Fsk signal demodulating system
Inventor: SAKATA TAKAO
IPC: H04L27/156
Filed: 1981-06-19
Abstract: PURPOSE:To demodulate a data signal without distortion from a PCM-coded FSK signal, through the decision of an accurate zero cross point, by interpolating a sampling value before and after the zero cross point. CONSTITUTION:A PCM code is serial-parallel-converted with a signal frequency- dividing a clock CK by 1/8 and inputted to registers REG1 and REG2 sequentially. When a polarity inversion detecting circuit DET compares signals from both the registors and detects zero crossing, a load signal is provided for a count circuit CT via an AND gate and delay circuits DEL1 and DEL2. On the other hand, a memory M generates an interpolation value(n) based on both signals of the REG1 and REG2 and presets the count circuit CT to this value. The circuit CT counts the clock CK and outputs K. A subtraction circuit SUB operates K-n and a discrimination circuit JU outputs a zero cross point signal based on the result of the SUB. An output signal with timing adjustments is measured for a time between zero cross points and is taken as demodulation signal for the FSK signal.
