<p>The method involves comparing received signals with two set of values using comparators (13, 14), where one set of the values ranges between the other set of the values. A presence of an insufficient modulation depth is considered if the received signal ranges between the values. The values are adapted with respect to average level of the received signal and supply voltage of a demodulator. Independent claims are also included for the following: (A) a method for detecting errors in a signal received in amplitude modulation (B) an amplitude demodulator comprising a capacitive unit.</p> |
