Question 756
|
The period of a signal is 100ms. What is its frequency in kilohertz?
|
10-1 kHz
|
|
|
10 -2 kHz
|
|
|
10-3 kHz
|
|
|
10-4 kHz
|
Question 756 Explanation:
First we change 100 ms to seconds, and then we calculate the frequency from the period (1 Hz=10-3 kHz).
100 ms=100*10-3s
= 10-1 s
f=1/T
=1/10-1Hz
=10 Hz
=10*10-3 kHz
=10-2 kHz
100 ms=100*10-3s
= 10-1 s
f=1/T
=1/10-1Hz
=10 Hz
=10*10-3 kHz
=10-2 kHz
Correct Answer: B
Question 756 Explanation:
First we change 100 ms to seconds, and then we calculate the frequency from the period (1 Hz=10-3 kHz).
100 ms=100*10-3s
= 10-1 s
f=1/T
=1/10-1Hz
=10 Hz
=10*10-3 kHz
=10-2 kHz
100 ms=100*10-3s
= 10-1 s
f=1/T
=1/10-1Hz
=10 Hz
=10*10-3 kHz
=10-2 kHz
