Metro City Planners proposes that a community conserve its water supply by replacing all the community's toilets with low-flush models that use only two liters per flush. Assume that there is about 1 toilet for every 3 persons, that existing toilets use an average of 15 liters per flush, that a toilet is flushed on average 14 times per day, and the cost to install each new toilet is $150.Write a program that would estimate the magnitude (liters/day) and cost of the water saved based on the community's population
Design lowpass IIR filter with the following specifications: Filter order = 2, Butterworth type Cut-off frequency=800 Hz Sampling rate =8000 Hz Design using the bilinear z-transform design method
1) Compute the average power dissipated through the resistor 2) compute RMS voltage across the resistor 3) compute V RMS^2/R. 4) prove that P avr=V RMS62/R for any periodic voltage waveform
A continuous time system has an output, y, which is given by y= 4sin( 4t+ f /2). It is sampled at a frequency of 4/f Hz. Determine the expression that correctly represent the discrete signal obtained after sampling and its value for n = 1
The laminated silicon steel core of a transformer has a mean length of 0.06 m and a cross section of 0.005 meter square. there are 150 turns on primary winding and 450 turns on the secondary. the input is 200 V rms at 50 Hz.
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
a) What is the key difference between coherent and non-coherent demodulation b) Explain the concept of differential encoding for BPSK modulation.
The waveform output by the signal generator in part (b) is changed so that the rectangular pulses have the same width but no longer are periodic. They occur at random intervals of time. Explain in words how the display on the spectrum screen would..
aluminum has the FCC crystal structure. Its atomic weight is 26.98g/mole, and its density is 2.70g/cm3. Determine the atomic radius of a single aluminum atom.
write a program that implement the system difference equation recursively, in "real-time" fashion, including the recursive update of variable samples(shift register). Compute and plot the response to x2[n] and x3[n], for one of the two systems, fo..
Doping is Nd=1x10^20/cm^3 on the n-side, and Na=1x10^18/cm^3 on the p-side. Find the equilibrium n and p values in the neutral regions on both sides as well as total depletion thickness in micrometer and peak electric field.
a) Express the s-domain impedance of this series combination as a rational function, b) Give the numerical value of the poles and zeros of the impedance and verify your calculation by matlab.
