Worked Solution & Example Answer:The output from a signal generator is connected to the input terminals of an oscilloscope - Scottish Highers Physics - Question 17 - 2015
Step 1
timebase setting and the horizontal distance between the peaks of the trace
Answer
To find the frequency of the signal displayed on the oscilloscope, use the timebase setting, which indicates how much time each division represents. Measure the horizontal distance between two successive peaks of the waveform in divisions. Multiply the number of divisions by the time per division to find the period (T) of the waveform.
The frequency (f) is then calculated using the formula:
f = rac{1}{T}
This formula shows that frequency is the inverse of the period, making it crucial to use both the timebase setting and the distance between peaks.
