Abstract

Circuit for processing an input signal based on at least one reference signal, comprising a phase locked loop demodulator configured to receive a speed control signal and said input signal and further configured to follow a frequency and/or a phase of said input signal at a speed, wherein said speed depends on said speed control signal; and a reference signal detector configured to determine said at least one reference signal and to set said speed by outputting said speed control signal to said phase locked loop demodulator, wherein, if said reference signal detector detects said at least one reference signal, said reference signal detector decreases said speed.
