A CRO screen has ten divisions on the horizontal scale.

A CRO screen has ten divisions on the horizontal scale. If a voltage signal 5 sin (314 t + 45°) is examined with a line base setting of 5 m sec/div, the number of cycles of signal displayed on the screen will be ___________cycles

The lines base setting = 5 msec/div

Input frequency =	50 × 10	= 2.5
	200

Now, Frequency of input signal = 314 = ω.
or 2 πƒ = 314 or ƒ = 314/2π = 50 Hz
Number of cycles of signal displayed

=	50 × 10	= 2.5
	200
