As the time moves forward and the study on the filters has increased, active filters have been a matter of discussion. Active filters are a group of electronic filters that utilizes active components like an amplifier for its functioning....

A filter can be defined with reference to various fields such as chemistry, optics, engineering, turbulence modelling, engineering, computing, philosophy, and signal processing. Let us consider signal processing filters, filter can be defined...

In digital signal processing, an FIR is a filter whose impulse response is of finite period, as a result of it settles to zero in finite time. This is often in distinction to IIR filters, which can have internal feedback and will still...

The name of Chebyshev filters is termed after “Pafnufy Chebyshev” because its mathematical characteristics are derived from his name only. Chebyshev filters are nothing but analog or digital filters. These filters have a steeper roll...

Op Amp or operational amplifier is one type of integrated circuit or microchip or chip, used to perform different operations like linear, mathematical, and nonlinear. An operational amplifier is a high gain amplifier by coupling directly...

In network analysis, knowing about the network theorem is very important for circuit analysis. So there are different network theorems available like Superposition, Tellegen’s, Norton’s, maximum power transfer, Thevenin’s, Compensation,...

In a circuit, reactance is the opposition that is offered through a capacitor (C) & inductor (L) to the AC current flow. It is much related to resistance however reactance changes through the frequency of the voltage source and it is...

In 1968, FAIRCHILD introduced a multi-stage amplifier, called an operational amplifier, available in the form of monolithic IC in small size, high reliability, low cost, and less power consumption. LF353N was developed by Texas instruments....

The configuration of an op-amp or operational amplifier can be done in two ways like inverting op-amp and non-inverting op-amp. In either of these configurations, the output is given back to its input which is called feedback. This feedback...

In electrical power systems, harmonics is a voltage otherwise current occurred at different basic frequencies. It is frequently considered as noise within the power line. The harmonics within the power system can be categorized into two...
