Abstract

PURPOSE:To obtain a miniature, lightweight and high-speed signal converter which converts signals into signals different in delay time region according to the frequency assigned to each channel of a frequency-divided multiple signal applied by using the elastic surface-wave sharp filter whose absolute value is nearly equal. CONSTITUTION:Elastic surface-wave sharp filter which is supplied with pulses from pulse generator 13, outputs them to frequency-converting mixer circuit 12. On the other hand, circuit 12, which is supplied with frequency-divided multiple signals, outputs them to elastic surface-wave sharp filter 15. Here, the sharpness of filter 14 is made nearly equal in absolute value to that of filter 15, so that outputs converted into different delay time regions according to the frequency assigned to each channel of the signal applied to input terminal 11 with appear at terminal 16. Therefore, high-speed signal conversion can be attained with a miniature and lightweight device.
