Notch Filter Circuits with Design Details
In this article I will provide a detailed explanation regarding how to design notch filters with precise center frequency and for maximum impact. Where Notch Filter are Used Notch filter circuits are normally used for suppressing, nullifying, or cancelling a particular range of frequencies in order to avoid an annoying or unwanted interference within a […]
Bipolar Transistor (BJT) – Construction, and Operational Details
A bipolar transistor or a BJT is a 3 terminal semiconductor device which is able to amplify or switch small signal input voltages and currents to significantly larger output signal voltages and currents. How Bipolar Junction Transistor BJTs Evolved During 1904–1947, the vacuum tube was unquestionably the electronic device of great curiosity and growth. In 1904, […]
Cathode Ray Oscilloscopes – Working and Operational Details
In this post I will elaborately explain how Cathode Ray Oscilloscopes (CRO) work and its internal construction. We will also learn how to use a CRO using the various controls and understand the graphical representations of the various input signals on the display screen of the scope. Importance of Cathode Ray Oscilloscopes (CRO) We know that majority […]
