| Question 2 |
If the period of a signal is 1000ms, then what is its frequency in kilohertz?
| 10 -1 Khz | |
| 1 KHz | |
| 10 -3 Khz | |
| 10 -2 Khz |
Question 2 Explanation:
Step-1: Frequency=1/time
Step-2: Time=1000 ms which is equals to =1 sec
Step-3: Frequency=1/1 sec
=1000/1000 sec
=1K/1000 sec
=10 -3 Khz
Note: 1 sec = 10 -3 ms
Step-2: Time=1000 ms which is equals to =1 sec
Step-3: Frequency=1/1 sec
=1000/1000 sec
=1K/1000 sec
=10 -3 Khz
Note: 1 sec = 10 -3 ms
Correct Answer: C
