<p>A signal processing system for performing compression and/or expansion of sound signals reproduced from a magnetic tape. The system includes a pair of analog shift registers, one of which is used for writing in an input reproduced sound signal under the control of a clock signal having a frequency corresponding to the speed of the reproducing magnetic tape and the other shift register being used for reading out the sound signal under the control of a standard clock signal. This system is further provided with compensating means for cancelling a D.C.-level deviation in the output signal.</p> |
