Module_3_PEC

The two types of AM transmitters are __________ and __________.

• low level

• high level

(a)   transmitters require only a few watts of power for transmission.

In (a)   transmitters, both carrier and modulating signals are amplified before modulation.

The (a)   amplifier matches the output impedance of the carrier oscillator.

A (a)   amplifier is used to amplify the carrier signal in high-level transmitters.

In the audio chain, the (a)   converts voice signals into electrical signals.

The (a)   amplifier is used to modulate the combined carrier and audio signals in high-level transmitters.

In a low-level AM transmitter, the (a)   class amplifier performs amplitude modulation directly.

The (a)   transmits the modulated signal as electromagnetic waves.

A (a)   amplifier is used in an AM collector modulator.
