Analog electronic - Lab Report Example A D.C. voltage of +15 and -15 volts is required to bias the circuit where the application of input voltage is done and the output measured on the DSO. The experiments done were linear operations of the op-amp, where the output is a linear proportion of the voltage difference at the input, up to the saturation point. These were inverting operation, non-inverting operation, differentiation and integration. Before the development of digital electronics technology, computers employed voltages and currents representing numerical quantities to perform calculations electronically. A varying voltage can represent a physical system’s force or velocity. Success of the inverting and non-inverting experiments would determine whether these amplifier configurations could be used to simulate the physical processes by electronically performing mathematical operations of addition, subtraction, multiplication and division in electronics such as calculators and computers. Reactive properties of capacitors were studied in the integration and differentiation experiments to determine whether they can be used to simulate variables that are related by calculus functions. Flow of current through a capacitor is a function of the rate of change of voltage and such a function is designated as differentiation in calculus. This is important in analog computing where for example in simulating a mechanical system, the voltage across the capacitor would stand for an objects’ velocity, the capacitor’s current representing the force to accelerate or decelerate the object and the capacitance of the capacitor being the mass of the object (The "operational" amplifier. 2015). The experiments are also important for the op-amp applications in signal processing, instrumentation and solid-state analog control systems. The capacitor in the forward path and feedback path enables real time differentiation and integration of signals respectively in these systems. Successful
