Problem Detail: What is the difference between encoding and modulation? I have seen these terms used sometimes inter-changeably and sometimes differently (the ratio is 50:50). Can somebody clearly explain this with some non-technical and technical examples both? I have searched this a lot on net and in the end I end up scratching my head.

Modulation: Way to send signals (information) from one place to another. exanmple: you have a carrier wave like a sine wave and your Information signal 10101010 or any analog signal you want to transmit. You simply just change the properties of carrier wave with respect to your signal. Like: AM, FM, ASK, PSK, QAM Encoding: Somthing else than modulation. It is representation of data. Example: 5Volts could be 1 or 0 according to logic (examples are Unipolar encoding, Bipolar Encoding).
