Demodulation system for angle-modulated wave picked up from a multi-channel record disc |
| abstract |
A demodulation system comprises a phase-locked loop for demodulating an angle-modulated wave picked up from a multichannel record disc. A circuit reduces the loop gain of the phase-locked loop to reduce the lock range width of the loop. The lock range falls within the bandwidth of the angle-modulated wave and prevents the occurrence of erroneous locking responsive to the harmonic components of a direct wave. An amplification circuit compensates for a frequency characteristic on the high frequency side of a signal demodulated by the phase-locked loop. |
