发明名称 Envelope detector for AM radio
摘要 A receiver for receiving an amplitude modulated (AM) signal may include a first and a second detector for detecting the maximum and minimum envelope values, respectively, of the received AM signal and an equalizer for periodically equalizing the maximum and minimum envelope values. A method for receiving an AM signal may include unidirectionally increasing a first output signal up to the maximum envelope value, unidirectionally decreasing a second output signal down to the minimum envelope value, and periodically equalizing the first and the second output signals.
