ABSTRACT:
A signal processing apparatus includes: (a) A signal treating unit for effecting signal treating functions to present a treated signal at an output. (b) A clock generator receiving a clock signal and using the clock signal for presenting an internal clock signal for use by the signal treating unit. (c) A clock simulating unit occasionally coupled with at least one of the clock signal and the clock generator provides a simulated clock signal generally similar to the internal clock signal when either of the clock signal or the internal clock signal is interrupted. (d) A control unit coupled with the signal treating unit, at least one of the clock signal input locus and the internal clock generator for selectively coupling one of the internal clock signal and the simulated clock signal for use by the signal treating unit.
