Sampling Theorem | Sampling In PCM | Digital Communication

The sampling theorem, also known as the Nyquist-Shannon sampling theorem, is a fundamental concept in signal processing and digital communication. Sampling is a process of converting a continuous-time analog signal into discrete-time signal. This conversion is done with the help of sampler. Sampling is the second step in Pulse Code Modulation (PCM) technique where we … Read more

What is transistor? Its Type working principle

What Is Transistor? A transistor is a three-terminal electronic device that regulates the flow of electrical current or amplifies electronic signals. It is typically made of semiconductor materials like Silicon (Si), Germanium (Ge). It consists of three layers or regions: the emitter, the base, and the collector. Transistors are used in electronic circuits to perform … Read more
