For the system specified by the following difference equation, compute the first five samples of the response to the input given as
x(n) = (0.7)^n u(n). y(n) = 0.5v(n-1) - 0.8y(n-2) + x(n) - 0.4x(n-1)
Due to the current, the temperature of the wire is raised by T in atime t. A number N of similar cells is now connected in series with a wire of the samematerial and cross-section but of length 2L.
Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz,
An asset with a first cost of $50,000 is depreciated by the MACRS method over a 10-year period. If the asset will have a $20,000 salvage value, its book value at the end of year two will be closest to
A capacitor of value C=10 uF(microfarads: where 1 uF=10^-6 F) has a voltage of 2 volts across it. Calculate the amount of charge Q,in coulombs,on each plate.
A byte containing 01100011 is right shifted (right-most bit first) into an 8-bit shift register with an initial state of 00110110 (01100011=>00110110) What does the shift register contain after three clock pulses
If the cutoff between "insecure" and "secure" were x amount of time, how long would a secure password have to be. State and justify your assumptions regarding the character set from which the password is selected and the amount of time required to..
A resistor R, capacitor C, and voltage source Vs= 100 cos 300t Vare all in series. If the average power dissipated by the resistor is 150 W and the rms capacitor voltage is $) V, determine R and C.
Suppose that without a 1k-ohm load an amplifier's output voltage is 5Vpp but when the 1k-ohm load is attached, it drops to 3Vpp. What is the output impedance of the amplifier
A signal has a fundamental frequency of 1000 Hz. What is its period? Assume the signal has a peak amplitude of 1 Volt and that the instantaneous power is equal to the square of the voltage, then compute the average power of the fundamental frequen..
From a large lot of new tires, n tires are to be sampled by a potential buyer, and the number of defectives X is to be observed. If at least one defective is observed in the sample of n tires, the entire lot is to be rejected
Examining frequency to time domain signals, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates t..
The voltage drops across three resistors in series are measured to be 10.0V, 15.0V, and 25.0V. If the largest resistor is 47.0 ohms, what is the value of the smallest resistor
