MODULE 1-2

the transmission, reception, and processing of information with the use of electronic circuits

• signal

• electronic communication

• digital modulation

A knowledge that is communicated between two or more points

• Modulation

• Digital Transmission

• Information

Also called digital radio

• Digital Analog Signal

• Digital Transmission

• Digital Modulation

In digital _, the carrier facility of can be a physical cable or free space

• Modulation/Radio Systems

• Transmission

What is the difference between digital radio systems and conventional analog modulation system?

• Digital radio systems' information signal is digital while Analog Modulation Systems' information signal is analog

• Digital radio systems' information signal is analog while Analog Modulation Systems' information signal is digital

• Digital radio systems' information signal is modulating signal while Analog Modulation Systems' information signal is analog signal

The amplitude and phase are varied proportional to the information signal

• ASK

• Quadrature Amplitude Modulation
