64 - ANSWER✔✔ If you have a 5uV signal amplitude and a 20uV noise amplitude,
how many averages would you need to get a signal to noise ratio (SNR) of 2:1?
1 16
2 20
3 64
4 100
A downward peak of 0.6 V - ANSWER✔✔ A differential amplifier with a Gain of
1,000,000 has a 0.2uV signal at its pos input and a 0.8uV signal at its neg input.
The output will be:
1 an upward peak of 0.6 V
2 a downward peak of 0.6 V
3 an upward peak of 1 V
4 a downward peak of 1 V
100 KHz - ANSWER✔✔ If the sampling rate of your system is 20uS, then the
highest freq signal that can be resolved is:
1 50 KHz
2 25KHz
3 20 KHz
4 100 KHz
, 5 - ANSWER✔✔ Your initial signal amplitude is 0.5 uV inside a background noise
of 2uV, what will the signal to noise ratio be after 400 averages?
1 100
25
32
4 0.5
5 mS - ANSWER✔✔ What is the period of a 200Hz signal?
1 200 mS
2 50 mS
3 5 mS
4 2 mS
15 - ANSWER✔✔ How many waves of a 60 Hz signal should you see in a 250mS
sweep?
1 15
2 12
36
43
