Abstract : An input signal, whose frequency is to be detected, is divided and sent into two arms. One arm applies a set phase and amplitude adjustment while the other arm has a phase response that is dependent upon the frequency. Both arms are fed to a phase detector whose output is used to indicate the frequency of the input. (Author)
