ABSTRACT:
A paging receiver and a method for minimizing spurious interference signals in the radio frequency (RF) stages and the intermediate frequency (IF) stages. The paging receiver includes a receiving means, a timing means, a voltage converting means, and a decoding means. A frequency for the timing signals generated by the timing means is selected to minimize spurious signal response. The timing signals are simultaneously applied to the decoding means and the voltage converting means. The frequency of the timing signal can be varied to minimize spurious signal response. The decoding means is notified of the timing signal frequency to effect the detecting and decoding of received coded information in real time.
