ABSTRACT:
A switching arrangement for converting analog signals into digital signals, and vice versa, is described. Conversions between pulse amplitude modulated (PAM) and pulse code modulated (PCM) signals are performed. In telecommunication systems having subscriber stations equipped to transmit and receive analog signals it is necessary to carry out these conversions to facilitate PCM transmission. An analog to digital converter is thus provided at each subscriber station for converting received digital signals into analog signals and analog signals to be transmitted into digital signals; the converter utilizes the iterative principle.
