ABSTRACT:
A system for analog-to-digital conversion provides a dynamic range in exc of 120 dB yet requires an output of only 9 bits. These bits are utilized to transmit a companded digital word format including sign information. Use of this companded output format results in significant transmit bandwidth reduction compared with transmit bandwidths required for conventional linear bit formats. This companding results in a worse case error of 3.125%.
