Automotivecircuits use two types of signals:â¢INPUT-provides information about operating conditions(switches, sensors)â¢OUTPUT-causes an electrical or electronic device to operate(lamps, LEDs, relays, motors)Input and output signals can be either digital or analog, depending onthe application.
You don't speak in a digital signal. A digital signal is a language of 1s and 0s that can be processed by mathematics. We speak in real-world, analog signals. While the digital signal processor can handle signals at incredible speeds, it needs an interface to the real analog world in which we all live. A chip called a data converter is that interface. A data converter takes a real-world signal, such as sound, light, heat or pressure, and turns it into a digital signal.
