Introduction to Transistors What is a Transistor? A transistor is a three-terminal semiconductor device that can control the flow of electric current. It consists of three layers of semiconductor material, typically silicon, with different doping levels. The three terminals are called the emitter, base, and collector in bipolar junction transistors […]
What is a Notch Filter? A notch filter, also known as a band-stop filter, is a type of filter designed to attenuate or reject a specific frequency or a narrow band of frequencies while allowing other frequencies to pass through unaffected. Notch filters are commonly used in various applications, such […]
