Using the random selection method described in Section 8.3.3, search for the phases of fi fty 1-mV amplitude tones such that the peak-to-RMS value is in a ratio of approximately 3.35:1. Provide a plot to illustrate your result. Investigate the sensitivity of the peak-to-RMS value by changing the phase of each tone by 1% and computing the change in the peak-to-RMS value.
you are asked to write an essay outlining the evolution of cpu. a report describing in detail the main hardware
A spaceship moves at a speed of 0.85 c away from theEarth. It shoots a star wars torpedo toward the Earth at aspeed of 0.80 c relative to the ship. What is the velocity of the torpedo relative to the Earth
A voltage transformer for use on an 11 kV system has a star connected primary. If the turns ratio is 100/1 what will be the residual voltage of the open delta winding?
The ac source has an rms value of 20 V and a frequency of 60 Hz. The diodes are ideal, and the capacitance is very large, so the ripple voltage Vr is very small. The load is a 100-Ω resistance. Determine the peak inverse voltage across the diode a..
If the transmitter operates at 4.12 MHz, find its internal impedance.
Write the mathematical expressions for the voltage vC and the current iC when the switch is closed. - Sketch the waveforms of vC and iC.
A certain two-terminal circuit has an open-circuit voltage of 12V. When R=225 ohms is attached, the voltage across the load is 8V. Determine the Thevenin resistance for the circuit
If a resistor is inserted into the breadboard with one leg at point A and one leg at point B, what resistance will an ohmmeter measure for that resistor? Why?
Design a digital notch filter of the form H(z) = (1+cz-1+dz-2)/ (1+az-1+bz-2), which has a notch at fo = 60 Hz and a 3-dB width of Δf = 20 Hz. The sampling frequency fs = 8 KHz. Determine a, b, c and d.
Explore the effect of variations in q and h by plotting temperature distributions, T(r), for a range of parameter values. Suggest an envelope of acceptable operating conditions.
An LVDT Is used to measure the axial deformation a simple bar.The uncertainty in this measurement is ± 0.025mm. A steelbar is to be used to measure a force of 1100N with an uncertaintyof 1 percent.
