Question 3

What is modulation?

Answer 3

The variation of a part of an EM wave for the transmission of information. Process of superimposing a low frequency onto a higher frequency signal.

Question 4

What is Pulse Code Modulation (PCM)?

Answer 4

PCM is used to convert analog signals into digital signals.

Question 5

What three processes are involved with PCM?

Answer 5

Sampling, Quantizing, and Encoding.

Question 6

What is the Fourier Transfer?

Answer 6

Used to convert a signal between the frequency and time domains.

Question 7

What is an Electromagnetic Wave?

Answer 7

Wave that is composed of oscillating magnetic and electric fields.

Question 8

What is EM (Electromagentic Radiation)?

Question 9

What kind of current creates waves?

Answer 9

Alternating Currency

Question 10

Difference between an Analog Signal and a Digital Signal?

Answer 10

Analog signal is a continuous wave that changes over a period of time. A digital signal is a discrete wave that carries information in binary form.
