Document Type and Number:
Japanese Patent JP3842269
Kind Code:
B2
Abstract:
In a transmitting/receiving apparatus (6) of a transmitting side, a signal from an input terminal (Ti) is inputted to a delta sigma modulator circuit (42), delta-sigma modulated thereby, thereafter packet-divided by a transmitter (12), and then transmitted, as digital signals (S3), to a network (2). On the other hand, the transmitting/receiving apparatus (6) serving as a receiving side includes a clock signal producing circuit (22) that is independent of the network (2). The sampling rate of a data sequence (S21) from a receiver (21) is converted, by a sampling rate converter (23), to a period designated by the clock signal producing circuit (22), and thereafter amplified and demodulated by a digital switching amplifier having the delta sigma modulator circuit (42).
