Consider an ideal inverting omp-amp, but with the feedback resistance replaced with a diode that follows the diode equation (I≈Iscexp(qV/kbT)) The anode of the diode is connected to the inverting node of the op-amp, while its cathode is connected to the output of the op-amp. Determine the expression of the output node potential as a function of the input node potential. What is the use of this circuit.
Show that the time displacement in a periodic function has no effect on the magnitude spectrum, but changes the phase spectrum by an amount of -nω0τ radians for the component of the frequency nω0 if the time displacement is τ.
Vo(t) = RC (dVi(t)/dt). Suppose you have a triangle waveform as input to the differentiator with 100pF capacitance and 100 Ohms. The peak to peak voltage of the triangle waveform is 10Vpp and its frequency is 100k Hz.
a sample of gas composed of 5.7 grams of carbon dioxide and 3.6 grams of neon in a container with volume 5.7L and temp 67 degrees Celsius. what is the pressure of the gas mixture
A ripple carry adder is made of full adder cells each having 1 unit of combinational delay. To convert a four-bit ripple carry adder into a four stage pipeline adder proceed as following.
Project on LFC using tuned FOPID. I have considered a two area model. Need help regarding implementation of GA MATLAB code for a two area interconnected power system for LOAD FREQUENCY CONTROL.
A special external data signal (DATA_READY) is asserted whenever each of the bits for X are available. In addition, another special signal (ENCODE) is asserted during the transmission of the data X indicating whether 2X+3 or 3X+1 should be compute..
