Demodulating circuit for data signal |
摘要 |
In a data signal demodulating circuit for demodulating data from a modulated signal burst in which a carrier signal is modulated by a data signal, noise elimination means is provided at at least one of the input and output of an AND circuit, to eliminate noise in periods during which there is no carrier present, by adding an output from a demodulator to an output from a carrier sense circuit, in order to completely eliminate noise occurring at the start and end of a demodulated data signal, and eliminate noise occurring during the rise time and fall time of the carrier sense circuit.
