A controlling variable is a motor speed that varies from 800 to 1750 rpm.
If the speed is controlled by a 25- to 50-V dc signal, calculate (a) the speed produced by an input of 38 V, and (b) the speed calculated as a percent of span.
Describe the process of hopscotching . Why are diagnostic codes not always able to identify the system problem?
A DSP engineer applies DFT to 500 data samples that are sampled at 250 Hz to plot the signal spectrum. What is the frequency that corresponds to the frequency bin number
3. For the circuit shown, calculate (see attachment for circuit) a. The input resistanceat the base of the transistor. b. Theinput resistance of the amplifier
A majority function is generated in a combinational circuit when the output is equal to 1 if the input variables have more 1's than 0's. The output is 0 otherwise. Design a 3-input (A, B, C) majority function. Use K-maps to simplify the circuit. D..
An atomic power reactor can deliver 300 MW. If due to fission of each atom of 92U235, the energy released is 200 MeV, - calculate the mass of uranium fissioned per hour.
The fourier transform of the triangular pulse x(t) is expressed as: X(w) = 1/w^2(e^jw - jwe^jw - 1) Use this information, and the time-shifting and time-scaling properties to find the fourier transform of the signal: y = x, -1
Suppose a radio frequency signal is sampled at fs = 500 MHz. What frequency bands from 250 MHz to 1000 MHz will alias into the FM band, 88-108 MHz

A transformer has its maximum efficiency of 0.98 at 20-kVA at unity power factor.
What information do you deduce from these expressions if A is a promoter, Ba is an activator protein, and C is the activator/DNA complex that makes the gene transcriptionally active?
A 10-bit 5-V ADC operates with a sampling frequency of 1 MHz. If a sinusoidal histogram test is to be conducted on this ADC, what should be the maximum frequency of the input signal so that the average minimum code count is at least 10 hits? 100 h..
