1. Cathode Ray Oscilloscope (CRO) Electronics & Telecommunication Engineering Micro Project Presentation

2. Introduction 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.

3. Working Principle The CRO works on the principle of using a cathode ray tube to display signals. • Electron beam is deflected horizontally (time base) • Vertically (input signal) • Produces waveform on the screen

4. Block Diagram of CRO [Insert Diagram of CRO here]

5. Advantages • High frequency response • Accurate waveform measurement • Visualization of signal changes in real-time • Multiple signal comparison

6. Disadvantages • Bulky in size • Expensive compared to simpler instruments • Requires skilled operation • High power consumption

7. Applications • Measurement of voltage, current, power • Signal waveform analysis • Testing electronic devices and circuits • Frequency and phase measurement • Communication system testing

8. Conclusion CRO is an essential instrument in electronics and telecommunication engineering that provides accurate visualization of signals and helps in circuit analysis and testing.
