Question

1. You count 11 cycles across 7.7 time divisions on an oscilloscope screen. The time sweep is set to 10 milli seconds. The voltage peak is measured to be 22 volts. What is the frequency? in Hz

2. You plot some data of Real Frequency versus HP Dial Frequency and get a linear trend of
y = 1.2 x + 160.
To what must you set the HP Dial Frequency in order to get a Real Frequency of 6940 [Hz]?

3. Look at the first picture of the two pictures above.
Frequencyy-axis is at 250 [Hz].
What is the Frequencyx-axis? in Hz

Explanation / Answer

frequency= no. of cycles per second

= 11/(7.7*0.01)

= 142.8571 Hz

2.   6940 = 1.2x+ 160

x= 5650

3. x-axis frequency = 250 Hz
