1. Name the 3 multivibrators whose purpose is to convert DC Energy to square
wave energy. - ANSWER Astable Multivibrator
Monostable Multivibrator
Bistable Multivibrator
2. Helps to convert DC energy to square wave energy - ANSWER Astable
Multivibrator
3. Converts DC energy to square wave energy - ANSWER Monostable
Multivibrator
4. Converts DC energy to square waves - ANSWER Bistable Multivibrator
5. What type of blocking oscillator is a monostable Multivibrator? - ANSWER
Trigger
6. How is the output frequency determined in a bistable Multivibrator? -
ANSWER The output frequency is one half the input trigger frequency.
,7. 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.
8. 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.
9. All FET biasing techniques accomplish two things: - ANSWER (1.) Place a
positive voltage on the drain to establish current flow.
(2.) Reverse bias the source to gate PN junction to control current flow.
10.The action of converting detected intelligence into sound waves that a
human can hear. - ANSWER Reproduction
11.The action of separating the low frequency intelligence from the high
frequency carrier. - ANSWER Detection
12.The ability of the receiver to isolate one station's frequency from the many
frequencies present at the antenna. - ANSWER Selection
13.Occurs when a transmitted electromagnetic wave passes through the
receiver's antenna. - ANSWER Reception
, 14.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
15.Which is the most widely used FET? - ANSWER Common Source
