- Step 1: Understand that communication systems send information over distances.
- Step 2: Know that information is often changed into a different form for transmission, called modulation.
- Step 3: Realize that modulation makes the signal suitable for sending over a medium (like air or cables).
- Step 4: Learn that a demodulator is a device that receives the modulated signal.
- Step 5: Understand that the demodulator's job is to change the modulated signal back to its original form.
- Step 6: Recognize that once the signal is demodulated, the original information can be accessed and understood.
