Title:
BROADCAST RECEIVING DEVICE
Document Type and Number:
Japanese Patent JPH09102756
Kind Code:
A
Abstract:
To provide a broadcast receiving device which can secure the receiving results containing a smaller number of noises.
A CPU 6 measures the receiving signal intensity right before the reception of signals at the transmitting frequency F1 to FN [Hz] (N: an integer larger than 2) and the frequency F1+A to FN+A [Hz] which are approximate to the frequency F1+FN and radio waves not transmitted. This measurement is carried out based on the AGC signal 12 of a short wave receiver 1. Then the transmitting frequency corresponding to the largest one of ratios of the receiving signal intensity set between the frequency FM (M: all numbers of 1 to N) and the frequency FM+A is set at the receiver 1, and the broadcast is received at this set frequency.
