F.M. Demodulator with waveform correction circuit |
| 摘要 |
An F.M. demodulation circuit can be rendered insensitive to amplitude, level and waveform variations of the frequency-modulated carrier signal by using a frequency-demodulator (33,37) tuned to half the frequency of the carrier and preceded by a divide-by-two divider (21).
