Abstract

PURPOSE:To obtain a demodulation output by separating an AM signal wave after frequency conversion into a carrier and side-band waves, by separately amplifying the carrier and one side-band wave and then by synthesizing both of them by a detecting circuit. CONSTITUTION:A high frequency signal induced by antenna 1 is amplified by high frequency amplifying circuit 2 and mixed and synthesized with an oscillation signal, generated by local oscillating circuit 4, by mixing circuit 3, which outputs a frequency-converted carrier and side-band waves. This signal wave output is passed through band-pass filter 9 to extract only either one of two upper and lower side- band waves, which is amplified by band amplifying circuit 11. From the signal wave after frequency conversion, only the carrier is extracted by band-pass filter 10 and amplified by band amplifying circuit 12. Then, the separately amplified side- band wave and carrier are synthesized and detected by detecting circuit 13, thus obtaining demodulated low-frequency signal 14.
