Suppose a factory has a vat with a sensor that outputs 1 when the vat is empty, a 0 otherwise. The vat also has a pump to empty it, and a control switch to activate the pump. Devise a circuit that turns the pump on when the switch is set to activate the pump and the vat is not empty.
Compare the maximum theoretical PCE for 980-nm and 1475-nm pumping in an EDFA for a 1545-nm signal. Contrast this with actual measured results of PCE = 50.0% and 75.6% for 980-nm and 1475-nm pumping, respectively.
Compute the system's transfer function and the solution of the differential equation when the input x(t)=2 *u(t). An LTI (linear, time invariant)instrument has the following impulse response: h(t)=[2*e -2t -e -t] *u(t)
Three single phase transformers rated at 100kVA, 13.2kV / 2.4kV are connected in wye -delta on a 3 phase, 18kV line. What is the maximum load that can be connected to the transformer bank
Every 64 cycles, the circuit outputs the average ofthe past 64 input V values, then in the next cycle begins a new calculation (in other words, its behavior repeats). During the cycles when the circuit is not outputting the average, itshould outpu..
Describe very briefly the function and essential features of each block - Identify all inputs and outputs by the use of I/O designation charts.
Work out the following problem: If the analog signal to be quantized is a sinusoidal waveform, that is, x(t) = 6 sin (6283t), and if the bipolar quantizer uses 8 bits, determine 1. Number of quantization levels; 2. Step size of the quantizer ; 3. ..
When this combination is connected across a battery, the current delivered by the battery is 0.330 A. When the 43.0 W resistor is disconnected, the current from the battery drops to 0.190 A. Determine the emf of the battery.
Draw a Moore-type state transition diagram for this counter modeled as a category 3 machine.
A 460-V, four-pole, 75-hp, 60-Hz, Y connected, three phase induction motor develops its full load induced torque at 1.2 percent slip when operating at 60 Hz and 460 V. The per phase circuit model impedances of the motor are
Problem 1: (a) Give three examples of each of natural (free) convection and forced convection which occur in industrial processes.
