Name the 3 multivibrators whose purpose is to convert DC Energy to square wave energy. - (answer)1.
Astable Multivibrator
2. Monostable Multivibrator
3. Bistable Multivibrator
Converts DC operating voltage to square wave - (answer)Multivibrator
What type of blocking oscillator is a monostable Multivibrator? - (answer)Trigger
How is the output frequency determined in a bistable Multivibrator? - (answer)The output frequency is
one half the input trigger frequency.
What is the purpose of a Schmitt trigger? - (answer)To convert any input waveform of any shape and
amplitude into square wave pulses of constant amplitude.
In a Schmitt Trigger when is output high; when is output low? - (answer)The output is high anytime the
input exceeds the threshold.
The output is low anytime the input signal is below the threshold.
The action of converting detected intelligence into sound waves that a human can hear. -
(answer)Reproduction
The action of separating the low frequency intelligence from the high frequency carrier. -
(answer)Detection

The ability of the receiver to isolate one station's frequency from the many frequencies present at the
antenna. - (answer)Selection
Occurs when a transmitted electromagnetic wave passes through the receiver's antenna. -
(answer)Reception
What are AM receivers? What does the AM broadcast band cover? - (answer)AM receivers are
electronic devices that pick up signals sent from AM transmitters.
Frequencies go from 535 KHz to 1605 KHz
What is Amplitude Modulation? - (answer)Occurs when the carrier frequency is altered in the amplitude
by the lower intelligence frequency.
How many circuits do the turner block contain? What does each one do? - (answer)Tuner contains 3
circuits.
(RF Amplifier- selects and amplifies one frequency from the many picked up by the antenna.
Local Oscillator- produces a frequency 455 KHz above the selected RF.
Mixer- produces four frequencies)
What is LO, RF, LO+RF, and LO-RF? - (answer)LO Frequency- 455 KHz
LO+RF- Adds 455 KHz to the RF.
RF- Given number
LO-RF- is also referred to as the intermediate frequency (IF).
