A digital signal processor uses a RAM for signal processing. This allows the transfer function to be easily changed by either hardwired circuitry or a microprocessor. Two RAMs per channel can be used, one processing the signal, while the other has its transfer function changed. The operations of the RAMs can be changed during a portion of the input signal, e.g. blanking times, when the switch over is not objectionable. |
