WebLTspice is designed from the ground up to produce fast circuit simulations, but there is margin in some simulations to increase the speed. Note, there may be trade-offs in accuracy using the methods described here. For further details on any of these approaches, please refer to the LTspice Help File (F1). To measure the effects of your changes, rev WebInstructions. This calculator computes one of SNR, THD or SINAD from the other two as specified by radio buttons located to the left of the quantity name. SINAD equals the RMS sum of THD + SNR. For the computed / entered SINAD, the corresponding RMS noise and the equivalent number of bits are shown in an output field at right. free in tray tests for interviews
