An otherwise-ideal op amp, known to have an open loop gain of 10^4 V/V , is measured in a circuit to have an output voltage of -3 V.
While it would be difficult to measure, what would you expect the voltage from the negative terminal to the positive terminal to be?
If the voltage at the positive terminal is known to be +100 mV, what is the voltage at the negative terminal?
Spectrum Analyzer, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the following display:
A cable TV company delivers video signals over coaxial cable to individual houses. Video signals occupy a bandwidth of 6 MHz and are stacked in frequency from 50 MHz to 656 MHz without guard bands
What are the incremental savings that result from increasing the efficiency of a PV collector by 1% in terms of collector area and costs? Assume that the PV module represents about 50% of the total PV system cost.
Transfer function : key informaiton, A linear time-invariant discrete-time system is excited by the input x[n] = d[n] + 2u[n-1] (d represents δ(delta)). The resulting output response with zero initial conditions is y[n] = ((0.5)^n * u[n]). De..
