# About Digital and Analog Signals

Perhaps, all the present day gadgets and electronic devices work on boolean expressions( 0 & 1), commonly known as digital values. Before the rise of boolean algebra, almost the electronic devices like TV,radio signals etc. used analog wave signals. One of the differences between digital and analog signals is that digital signals are discrete (i.e. discontinuous),while analog signals are continuous waveforms.
