In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

In 1938, the Journal of Scientific Instruments published details of a comparator circuit that converted a slowly varying input signal into an abrupt change in output voltage. Based on cross-coupled ...

Window comparator: The circuit consists of two amplitude comparators and some diodes and resistors. A high level signal with a potential level above a specified value VH is equivalent to a positive ...

The Equal Pay Act allows employees to bring claims of pay discrimination based on gender by alleging that they were paid less than employees of a different gender who perform the same or similar work.

Fig 1. The traditional window comparator with a single op amp has interactions between the output and the reference voltage that creates uncertainty in its hysteresis window width. Fig 2. Adding a ...

Louisa Johnson, James Swartz Jr. In the case presented, the employer Rural gave light-duty assignments to four employees who had lifting restrictions due to injuries on the job. But when Durham ...

A simple to use window comparator can make short work of integrator, antiwindup, and reset circuits. Control systems that incorporate an integrator stage need some ...

This circuit compares two 4-bit binary inputs, A[3:0] and B[3:0], and checks if they are equal. Working Inputs: Two 4-bit numbers A (A3 A2 A1 A0) and B (B3 B2 B1 B0). The comparator checks each ...
