摘要

Within an AM receiver a noise peak detection circuit (1) generates a noise peak indication signal to allow the blanking of the noise peak. The noise peak indication signal is derived by a noise peak detection on basis of an orthogonal component (n alpha ) of an input signal corresponding the received AM signal, which orthogonal component (n alpha ) has an orthogonal relation to an information component (m.v(t1)) of the input signal.
