Design an inverting op-amp circuit for which the gain is -5V/V and the total resistance used is 120kΩ
An optical fiber is to be used to capture the light signal in a particular experiment. If the core of the fiber has an index of 1.46, and the cladding index is 1.457, what is the maximum angle of incidence of light that is accepted by this fiber
An oscilloscope shows the period of an ac waveform to be 3.5 horizontal divisions when the timebase control is set to "10 ms/Div". What is the measured period and frequency of the waveform
For input signal voltages between these limits, the input should pass unaltered to the output. The peak current drawn from the input source may not exceed 1mA. You may use any circuit component we've studied except opamps.
The fiber has a loss of 0.25 dB/km, and there is a splice with a loss of 0.1 dB every km. The coupling loss at the receiver is 0.5 dB, and the receiver uses an InGaAs APD with a sensitivity of -39 dBm. Find the system margin.
Determine the value of the constant c such that the following functions are valid probability functions: A. p(x) = cx/20, x = 1,2,3,4,5,6 and zero elswhere. B. p(x) = c(X^2 + 1), x = 1,2,3,4,5, and zero elsewhere.
Design a simple current divider that will reduce the current provided to a 1k Ohm load to 20% of that available from the source.
A lamp of 100 candela is placed 1 m below a plane mirror which reflects 90% of light falling on it. The lamp is hung 4 m above ground. Find the illumination.
A constellation diagram has four points located at (2,2), (-2,2), (-2, -2), and (2, -2) on the I(in-phase)-Q(quadrature phase) plane. Find the value of peak amplitude and the type of modulation this diagram represents.
Design a 2-digit 24 second "shot-clock" countdown timer with pushbutton controller.
The NF (dB) is defined as 10log(SNRin/SNRout) - in the unit of dB. If we are given the values of SNRin and SNRout in dB unit, how do we calculate NF (dB) in terms of dB, and how do we calculate NF in term of a pure ratio
discharge a capacitor of 1mF charged with a voltage of 1 volt we connect it, at time t = 0, with a esistor of R ohm. When we measure the voltage we find it to be V(r) (t) = e ^(-t) u(t). Determine the resistance of R. If the capacitor has a capaci..
A gallium-arsenide crystal at 200K containing only donor impurities was found to have hole concentration to be one fifth that of the electron concentration. Determine the actual carrier concentrations and the doping concentration of the crystal.
