A PID controller consists of the proportional, integral, and derivative blocks connected in parallel. It brings together the characteristics of its building blocks and can […]
The linear position transducer consists of a resistance enclosed in a metal container in which a rod flows. […]
The TIG (Tungsten Inert Gas) welding method is one of the inert atmosphere electrical welding techniques. […]
Example of conditioning circuit with the use of two PT100 temperature transducers […]
The forced response of a DLIT system can be done by iteratively solving a difference equation of order n, or by the discrete convolution of the input with the impulse response of the system. […]
In the past few decades, analog controllers have often been replaced by digital controllers whose inputs and outputs are defined at discrete time instances. […]
The transfer function of a second-order IIR filter is obtained. […]
After seeing its behavior over time, we derive the transfer function of an FIR filter and the conditions for it to introduce a linear phase shift with frequency. […]
The output of an FIR filter at a certain moment is given by the linear combination of the input samples taken in a finite number of previous moments. […]
Introduction to digital filters, part one. Advantages over analog filters. […]
