Abstract

PURPOSE: To secure the reception with a high sensitivity and with no tracking error by comparing the output of the IF amplifier circuit with the reference voltage and then giving the D/A conversion to the output to be used for the tracking correction of the tuning circuit.
CONSTITUTION: The reception signal sent from the antenna is amplified through signal tuning circuit A and then mixed with the local oscillation signal of local oscillation circuit B to then receive mixture and frequency conversion at frequency conversion circuit C and to be then changed to IF of 455K Hz. Here comparator circuit 5 gives a comparison between the output of IF amplifier circuit 2 and reference voltage V to supply the output to CPU6. The output given from CPU6 undergoes the D/A conversion, and the output is used for the tracking correction of circuit A. As a result, the high-sensitivity reception is ensured with no tracking error caused.
