摘要： A PCM coder and decoder circuit for use in a subscriber line interface circuit of a telephone communication system has a digital balancing network for removing any echo signal. The digital balancing network is formed by series-connecting a first balancing circuit having characteristics corresponding to the fixed characteristics of a coder, decoder, etc. and a second balancing circuit having characteristics corresponding to variable characteristics of an external circuit including two-wire transmission line which is connected to the coder and decoder circuit. Thus, a replica of an echo signal is precisely produced, and the circuit configuration is simplified.

摘要： An oversampling type digital-to-analog converter which has a light gradient overload and a high signal-to-noise ratio in spite of a comparatively low sampling frequency.In a digital-to-analog converter wherein the difference between an oversampled digital input signal and a feedback signal is taken, such differences are integrated, the integral value is quantized to obtain the feedback signal, and part of the feedback signal is used as an analog output signal; a circuit for the quantization is constructed of a circuit which converts the integral value into a digital signal smaller in the number of bits than the digital input signal, and the feedback signal is obtained by integrating the outputs of the quantization circuit by means of a digital integral circuit.
