Question

Practice Quizni The graph below shows an oscilloscope trace of a sinasoidal vollage signal as a function of time For the graph shoun below the vertical vols per division is 1.0 Viv and the hoeiaontal time per division is 20 msocidiv. For this signal: a) (2 points) What is the peak-6o-peak veltage of the sipnal? b2points) What is the voltage amplitude for V) in volts of the signal c)(2 poinbs) What is the rms value of the signal in vos? ) 2 points) What is the period of the signal in milliseconds? c) (2 points) What is the froquency of the signal?(Inclue the units

Explanation / Answer

Only one question can be posted as per chegg guidelines

1.

a)

From the graph ,peak to peak voltage is

VP-P=6 vertical divisions=6 V

b)

Voltage amplitude or maximum voltage

Vmax=VP-P/2 =6/2 =3 V

c)

Rms Voltage

Vrms=Vmax/sqrt(2) =3/sqrt(2)=2.12 Volts

d)

Period

T=5 Horizontal divisions =5*2 =10 ms

e)

frequency

f=1/T =1/0.01 =100 Hz
