PDM-PAM conversion system

The requirements and methods for changing pulse amplitude modulation to pulse duration modulation are met by a PDM to PAM Converter. This unit functions over a wide range of input signals and can include, if desired, servo correction of zero and full scale references. As part of an integrated system, the converter is augmented with an all electronic commutator simulator, gate generators, and patching facilities. The converter features provisions for switching in the absence of up to five information channels, protection against generation of false master pulses, and a compensated duty-cycle circuit.
