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.
\(Time \space period={1\over Frequency}\)
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.
\(f={1\over T}\)
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.
