Concept:
Pulse Width Modulation (PWM):
As mentioned PWM is short form of Pulse Width Modulation in which width of pulse is proportional to amplitude of the modulating signal.
Pulse Width Modulation (PWM):
As mentioned PWM is short form of Pulse Width Modulation in which width of pulse is proportional to amplitude of the modulating signal.
Following are the benefits or advantages of PWM:
- Noise interference is less or minimum.
- The system is moderate in complexity to implement.
- It has moderate power efficiency among all three types.
- It supports higher power handling capability.
- It has high accuracy due to the fact that it can be self-calibrated.
- It has high S/N ratio.
- It has the ability to simultaneously record information from a large number of channels.
Following are the disadvantages of PWM:
- Instantaneous power of transmitter varies.
- The system requires semiconductor devices with low turn-ON and turn-OFF times. Hence they are very expensive.
- High switching losses due to higher PWM frequency.
From the given statements, 'It has a less complex electronic circuitry and therefore the reliability of such system is high' is NOT an advantage of Pulse Duration Modulation (PDM) recording.

Which of the following is NOT an advantage of Pulse Duration Modulatio...
Pulse Duration Modulation (PDM) Overview
Pulse Duration Modulation (PDM) is a technique used in various recording and transmission systems, particularly in electronics and communication engineering. While PDM offers several advantages, not all claims about its benefits are accurate.
Reasons Why Option A is NOT an Advantage
- Complexity of Circuitry:
Contrary to the assertion in option A, PDM systems can involve complex electronic circuitry. This complexity arises from the need for precise timing and control mechanisms to modulate pulse durations accurately. Although this complexity can lead to advanced functionalities, it does not inherently guarantee high reliability.
- Reliability Factors:
The reliability of a system is influenced by various factors including design quality, component selection, and operational environment. A more complex system can introduce more points of failure, potentially decreasing overall reliability.
Other Advantages of PDM
- Simultaneous Multi-Channel Recording:
PDM can efficiently handle multiple channels, allowing for the recording of diverse data simultaneously without significant interference.
- High Signal-to-Noise Ratio (S/N):
PDM techniques can achieve a high S/N ratio, which enhances the quality of the recorded signal and reduces noise interference.
- Self-Calibration:
PDM systems can be designed for self-calibration, ensuring high accuracy in the recorded output by adjusting to variations in the system automatically.
Conclusion
In summary, while PDM possesses numerous benefits, the assertion in option A regarding less complex circuitry and high reliability is misleading. Understanding these nuances is crucial for leveraging PDM effectively in electronic systems.
