My biggest, most complex PCB design so far. This is the excitation section of the vocoder and includes two oscillators, a noise source, a mixer, precision rectifier, low pass filter and an analogue switch. I've introduced a ribbon cable connector which will distribute signals into and out of the 28 bandpass filter circuits.
