Detailed Description

Simple 1st order All-digital Sigma Delta converter.

All-digital sigma delta converter Performs Sigma Delta function in digital domain for use when output will go to a (nbit_out) D/A converter. Default is 8 bits in, 1 bit out. After construction, call single() to get output. Multirate performed by calling single() with same input at the higher sampling rate.
