Table of Contents. Analog circuits are circuits dealing with signals free to vary from zero to full power supply voltage. This stands in contrast to digital circuits, which almost exclusively employ âall or nothingâ signals: voltages restricted to values of zero and full supply voltage, with no valid state in between those extreme limits.
A simple analog telephone line is a voice circuit historically made from copper wire that runs from your local phone company's Central Office (C.O.) building to your business location. The central office houses telephone switching equipment that connects you to the Public Switched Telephone Network (PSTN).hen you speak into the handset of your phone, the microphone converts the sound waves into analog electrical waves. These waves propagate over the telephone line to their destination. The receiving phone then converts the the electrical signals back into sound waves through the speaker of the handset.
