SSB Modulation

Question 1

What kind of input signal could be used to test the amplitude linearity of a single-sideband phone transmitter while viewing the output on an oscilloscope?

Answer 1

A two-tone audio-frequency sine wave.

Question 2

What does a two-tone test illustrate on an oscilloscope?

Answer 2

Linearity of a SSB transmitter.

Question 3

How can a double-sideband phone signal be produced?

Answer 3

By modulating the supply voltage to a class C amplifier.

Question 4

What type of signals are used to conduct an SSB two-tone test?

Answer 4

Two non-harmonically related audio signals that are within the modulation band pass of the transmit
