    The said modulation adopts low frequency wave as the carrier. While high frequency wave as the signal wave. Low frequency wave carrying the high frequency signal is transmitted, therefore, properties of low frequency is possessed. Since the threshold detector circuit is adopted, aims of large magnitude of compressing band width can be attained.
