## What is a diode? What is the application of it?

What is a diode? Describe the theory of diode operation. What is the application of it? What are the types of diode? List them and draw their symbol. Diode: When a p-type semiconductor and an n-type semiconductor are joined, the device is known as a diode. It has two terminals known as electrodes, one electrode each from p‐region and n‐region hence called diode (Di + … [Read more...] about What is a diode? What is the application of it?

## How analog signal can be converted into a digital one?

Analog signal can be converted into a digital signal: Ans. An Analog signal can be converted into a digital signal by following the procedure as shown in the figure below.

## What is different analog and digital signal?

Different analog and digital signal: Analog signal : (i) Unit step signal: (ii) Unit ramp signal: The unit ramp signal is defined as, (iii) Unit impulse signal : The impulse signal is a signal with infinite magnitude and zero duration, but with the unit area. The unit impulse function is also known as the Dirac delta function. (iv) Exponential signal … [Read more...] about What is different analog and digital signal?
