Operational Amplifier as Differentiator & Integrator

The Operational Amplifier as Differentiator & Integrator from Glass Agencies under the EROSE brand is a versatile and educational laboratory apparatus designed to demonstrate the fundamental applications of operational amplifiers in signal processing. This apparatus provides students, trainees, and researchers with hands-on experience in understanding how op-amp circuits can perform mathematical operations such as differentiation and integration on input signals, which are essential in analog computation, waveform shaping, and control systems. The setup is carefully assembled with operational amplifiers, resistors, capacitors, and clearly labeled input and output terminals, allowing users to easily construct and observe differentiator and integrator configurations. In the differentiator mode, the circuit produces an output voltage proportional to the rate of change of the input signal, effectively highlighting how rapid variations in input can be amplified, which is useful in edge detection, waveform analysis, and high-pass filtering applications. In the integrator mode, the circuit provides an output voltage proportional to the integral of the input signal over time, demonstrating applications in signal averaging, low-pass filtering, and analog computation. A regulated power supply ensures stable operation, while built-in protective elements safeguard the apparatus from overvoltage, overcurrent, and incorrect connections, enabling safe and repeated use in classrooms and laboratories. Accessible test points allow observation of input and output waveforms using oscilloscopes, multimeters, or data acquisition systems, enabling detailed analysis of amplitude, phase shift, and waveform transformation. Users can vary input signal types, frequencies, and component values to study the effect on output characteristics, gaining practical insight into operational amplifier behavior, linearity, and response. The compact and robust construction ensures durability, stability, and long-term usability in educational institutes, technical training centers, and research laboratories. Glass Agencies maintains strict quality control to guarantee reliable performance, accuracy, and operational safety. The Operational Amplifier as Differentiator & Integrator apparatus provides an interactive platform for studying analog signal processing, waveform transformation, and mathematical operations using op-amps. It is an essential tool for electronics education, laboratory experimentation, and research, offering students and researchers practical experience in differentiation, integration, and applied analog circuit applications, making it a valuable addition to modern electronics laboratories and technical training programs.
