Class Information
Number: 341/153
Name: Coded data generation or conversion > Analog to or from digital conversion > Digital to analog conversion > Using weighted impedances
Description: Subject matter where the conversion utilizes a network comprising a series of impedances each of which has a value such that the current through it is representative of the value of a particular bit position of the digital input signal and a summing circuit for adding the currents flowing through the impedances to develop a signal representative of the digital input signal.
