Digital signals: They are wither ON or OFF state. That is 0 or 1. Like if a lamp is glowing or not.

Analog signal is a range of values that lie between ON and OFF. Like the position of gate between the "OPEN" and "CLOSE" position. Like, 45 degrees open. So the signal is between 4 to 20 mili-amps normally (4 amps is FULLY OPEN and 20 amps is FULLY CLOSED). 4 amps corresponding to 0% and 20 amps for 100%.

Ceiling fan motor wiring Hi, I have 2 ceiling fans broken. The receiver/control units burned out due to lightening. One Harbor Breeze and one Hunter's I took them apart (remove receiver units). Now on both of the motor I see 4 wires coming out from each motor I really want to know the function of each wire. Are there anyway I can test to see which is which? After searching forums I know these 4 wires are from 2 sets of coils inside the motor, one is Start winding and the other is Runing winding I could not find the receiver/control unit any where, so I am planing to buy Capacitors and universal remote controls to make the fans run again. Anyone has any idea how to do the wiring, please help Thnks
