Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFTo measure the frequency of a waveform using a Cathode Ray Oscilloscope (CRO), the following parameters are required:
1.) Timebase Setting
- The timebase setting on the CRO determines the horizontal scale of the display. It tells you the time duration represented by each division on the horizontal axis.
- By knowing the timebase setting, you can calculate the period of one cycle of the waveform.
2.) Number of cycles displayed
- Frequency is the number of complete cycles a wave makes in a given amount of time.
The time period can be calculated by multiplying the timebase setting by the number of divisions (or cycles) displayed.
Time Period = Timebase Setting × Number of Cycles Displayed
Additional Information Parameters of the sinusoidal wave
1.) Period (T)
The time taken by a sinusoidal wave to complete one complete cycle is known as the period.
2.) Frequency (f)
The number of cycles made by a sinusoidal wave in one second is known as the frequency.
3.) Amplitude
The maximum value of the sinusoidal wave is known as the amplitude.
4.) Time constant
The time required by the wave to reach 63.2% of maximum amplitude is known as the time constant.
