Q3. Define sampling theorem
Ans. 
Sampling theorem states that a continuous signal can be accurately represented by discrete samples if the sampling rate is at least twice the highest frequency component of the signal.
• The sampling theorem, also known as Nyquist-Shannon sampling theorem, is essential in digital signal processing.

• It states that in order to accurately reconstruct a continuous signal from its samples, the sampling rate must be at least twi...read more

Q1. How is HIL programming different from normal software simulation?
Ans. 
HIL programming involves testing software with real hardware components, while normal software simulation uses virtual components.
• HIL programming requires physical hardware interfaces for testing

• Normal software simulation uses virtual components to mimic real-world scenarios

• HIL programming provides more accurate results due to real hardware interactions

• Normal software simulation is more cost-effective and easier to set
