Filed: 1981-03-31
Abstract: PURPOSE:To attain the quick tuning to the arrived signal, by obtaining a tuning indicating signal by comparing the outputs obtained by giving the wave detection to the signals obtained by giving the frequency conversion to the unknown arrived signal and passed through two filters of a narrow band and a wide band respectively. CONSTITUTION:The frequency of an arrived signal X is converted by a mixer A and a  local oscillator I and then branched into two parts. One of these two signals receives  the wave detection through a wave detector C through a filter J of a narrow band;  while the other signal receives the wave detection by a wave detector G through a filter H of a wide band respectively. In case when the arrived signal does not pass  through the filter H, the signal is set at zero or at the noise level; while the output of  the detector G is larger than that of the detector C. The ratio between these two outputs becomes minimum in case when the frequency component having the strongest spectrum energy among the frequency components of the arrived signal that received  the conversion of frequency passes through the filter J. The output of the detector C is  amplified by a level controller K and then compared with the size of the detector G  through a comparator E. Then a tuning indicating signal Z is delivered by the output  of comparison, and a switch F is actuated by the signal Z to obtain an output Y.
