Arrangement for carrier recovery in carrier frequency video and data transmission systems |
| abstract |
An arrangement for carrier recovery in carrier frequency video and data transmission systems comprising transmitting and receiving converters which operate with over modulation has a suppressed carrier modulator in the transmitting converter with a Nyquist filter connected to its output for creating a vestigial side band and a pre-emphasis circuit connected at the input for strongly damping low frequency signals so that a degree of modulation of less than 100% results in carrier frequency signals. The receiving converter includes a carrier recovery device having a band pass filter followed by a limiter. The limiter is connected to a demodulator and a de-emphasis circuit is connected to the output of the demodulator. |
