Full wave amplitude modulation detector circuit |
摘要 |
A current comparator is supplied with differential currents based upon an amplitude modulated radio frequency carrier. The comparator outputs are summed in a combining stage the output of which will contain a direct current proportional to the average carrier level and a current variation which represents the carrier modulation. The circuit provides very efficient detection of the modulated carrier.
