Question

What frequency does the sinusoidal signal have that occupies 5 horizontal divisions and 3 vertical divisions on a CRO for a full cycle if the time base is set to 1 ms per division?

a) 3 Hz
b) 5 Hz
c) 8 Hz
d) 15 Hz

Answer 1

The frequency of the sinusoidal signal is 200 Hz.

Step-by-step explanation:

To find the frequency of the sinusoidal signal, we need to determine the time period first. Each horizontal division on the CRO represents 1 ms, so 5 divisions would be 5 ms. Since the time base is set to 1 ms per division, the time period would be 5 ms. The frequency is the reciprocal of the time period, so the frequency would be 1/5 ms or 200 Hz.
