Abstract

PURPOSE:To secure an easy alteration for the signale-frequency band receiver into the multi-frequency band receiver by obtaining the oscillation frequency of the local oscillator through satisfaction of the prescribed simultaneous equations in case the full frequency bands of AM and FM are received. CONSTITUTION:The relation of NP1=P2+ or -F3 is satisfied when the phase control loop has the normal operation, where P1 is the frequency of the signl applied to input terminal 1, P2 is the oscillation frequency of voltage control oscillator 5, F3 is the oscillation frequency of offset frequency oscillator 6 and N is the division ratio of divider 9 each. And in case the IF of AM and FM are referred to as F1 and F2 along with the reception frequency bands of the AM and FM bands referred to as A1-A2 and B1-B2 respectively, N and F3 are set for the oscillation frequency of the local oscillator so that either one of the simultaneous equations may be satisfied in case the full frequency bands of AM and FM are received. In this way, the receiver to receive the single-frequency band can be changed easily into the receiver to receiver the multi-frequency band.
