Abstract
A phase adjusting circuit for a demodulator is provided. The circuit comprises an A/D converter for sampling an input analog signal at an interval shorter than the Nyquist interval and converting the sampled analog signal to a digital signal, a digital filter for narrowing the frequency band of the digital signal to output a filtered digital signal, a digital sampling/holding circuit for decimating sampling components of the filtered digital signal to output a decimated digital signal, and a phase locked loop circuit for detecting a phase error of the decimated digital signal and controlling the number of sampling intervals to be skipped by the digital sampling/holding circuit.
