Correct Answer: electrostatic
Correct Answer: does not wait for acknowledgement after sending a block
Correct Answer: 0.7 V across each depletion layer
Explanation:
Since there are two p-n junctions, there are two depletion layers and 0.7 V across each layer.
Correct Answer: False
Explanation:
It uses high frequency inverter.
Correct Answer: True
Correct Answer: 2 quadrants
Correct Answer:
Explanation:
.
Correct Answer: one full wave of output
Explanation:
Since output frequency is 2f, one half wave of input must equal one full wave of output.
Correct Answer: It is a unidirectional voltage
Explanation:
Impulse is unidirectional (either positive or negative).
Correct Answer: False
Explanation:
It has one sign flag S.
