Equation Reference: ECE210 textbook, page 97, Analog Signals and Systems by Kudeki and Munson. As its voltage approaches the source voltage (the 5V voltage source shown on the left), the current flowing into the capacitor decreases. The capacitor passes high frequencies (and sudden changes), causing the + input of the op-amp to be closer to the input. Several of us on these electronic websites use the free LTspice from Analog Devices which is one of the best free ones available. This is a half adder , which adds two binary numbers and produces a two-digit binary result.

Three identical RLC circuits are being driven by three different frequencies. This will load the subcircuit model. Falstad. The green color indicates positive voltage. Since the integral of a sine is a negative cosine, and the integral of a cosine is a sine, we can generate both waves by feeding the output of each integrator into the input of the other. . This is an electronic circuit simulator. Current Circuit: Simple, with distortion. In the middle case, the impedance is purely resistive and has no reactance. This is a simple sawtooth oscillator using a 555 timer chip . The transistor does two things: 1) it isolates the zener current from the LED current; 2) it amplifies the zener current so the turn on happens more or less when the zener starts to conduct instead of being a soft turn on. Analog Filter Applet Demonstrates electronic filter circuits. Actually many engineers prefer more accurate and stable engine (like in NL5 for example) and. When both inputs are high, the two transistors on the left are in reverse active state. The Falstad simulator does a hell of a better job in showing how this works.
