1. Cathode Ray Oscilloscope (CRO)
A Cathode Ray Oscilloscope (CRO) is an electronic device used to display and
analyze the waveform of electronic signals. It converts electrical signals into a
visual graph of voltage vs. time, helping engineers and technicians observe signal
properties.
Working Principle:
The CRO works on the principle of using a cathode ray tube to display signals. An
electron beam is deflected either horizontally (time base) or vertically (input signal)
to produce the waveform on the screen.

Advantages: High frequency response Accurate waveform measurement
Visualization of signal changes in real-time Multiple signal comparison
Disadvantages: Bulky in size Expensive compared to simpler instruments
Requires skilled operation Power consumption is relatively high
Applications: Measurement of voltage, current, power Signal waveform analysis
Testing electronic devices and circuits Frequency and phase measurement
Communication system testing
Conclusion:
CRO is an essential instrument in electronics and telecommunication engineering
that provides accurate visualization of signals and helps in circuit analysis and
testing.
