This application note describes the basic issues thatneed to be addressed in order to implement digital signalprocessing systems using the PIC16C74 andprovides application code modules and examples forDTMF tone generation, a 60 Hz notch filter, and asimple PID compensator for control systems. Theseroutines can also be used with other PIC16C6X andPIC16C7XXX processors with minor modifications andthe addition of external analog I/O devices.
