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?
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. Fig. Block diagram of the analog to digital converter Sampler: It converts continuous amplitude continuous-time signal into continuous amplitude discrete-time signal. Quantizer: It converts … [Read more...] about How analog signal can be converted into a digital one?
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?
Q: What is the signal? Define Amplitude is an important variable parameter of the signal. What kind of operations can be performed with amplitude? The signal is a function that conveys some information. A signal is defined as a physical quantity that varies with time, space, or any other independent variable. Example : (i) Electric voltage or current, such as radio signal, … [Read more...] about What is the signal? Classification of signals
