communication system the receiver, using the same, and sampling rate conversion means

摘要

Transmitting and receiving apparatus on the transmitting side (6), after the input delta-sigma modulation circuit (42) and the delta-sigma modulation, is divided into packets by (12) and a transmitter, the signal from the input terminal Ti is a digital signal S3, it is sent to the network (2). On the other hand, sending and receiving apparatus comprising a receiving side (6) is provided with a (22) a clock signal generating circuit independent network (2), the sampling rate converter data sequence S21 from the receiver (21) and (23) , after the sampling rate is converted to direct cycle (22) the clock signal generating circuit, the digital switching amplifier with (42) the delta sigma modulation circuit, it is amplified and demodulated.
