Abstract:
A combination comprising:a first section and a second section, each section having an input and an output; the first section including circuitry for receiving digital signals at its input, processing these digital signals and producing analog signals at its output corresponding to the digital signals at its input; the second section including circuitry for receiving analog signals at its input, processing these analog signals and producing digital signals at its output corresponding to the analog signals at its input;a lock-out circuit coupled between said first and second sections for disabling the second section while signals are being propagated in the first section and for disabling the first section while signals are being propagated in the second section; andmeans for providing a delay to the propagation of signals along a signal transmission path between the output of the first section and a point along the transmission path of the second section.
