1- Find F(s) for = A[ a cos(ßt) + b sin(ßt)] u(t) and plot and the poles and zeros in the S- plane
2- find f(s) for = 2d(t) +4e^-2t cos(2t) u(t) and plot and the poles and zeros in the S- plane
3- find f(s) for = 10[3-6t-4e^-2t] u(t) and plot and the poles and zeros in the S- plane
4- find f(s) for = [10e^-3t - 5e^-5t ] u(t) and plot and the poles and zeros in the S- plane
Design a second-order band-pass IIR filter with center frequency of 450 Hz when the sampling frequency is 2,000 Hz. In order to ensure the filter stability, set the poles at 0.96 radial distant from the origin
Write a program that asks a user to input (one at a time) the four numbers to fill a 2x2 matrix. For each number entered, make sure the user knows which number is being entered.
If we wish to design a communication system which carries voice securely, we need to ensure that others cannot tap into the conversation. In digital transmissions, we can do this by encryption.
A coiled tungsten wire of diameter 50um and length 10cm is glowing at a temperature of 2000°C within an evacuated light bulb. Determine the irradiance of the filament and the fraction of irradiance within the visible range of wavelength.
Silicon has an absorption co-efficient of 850 cm-1 at a wavelength of 805 nm. Light of intensity 1 W/m2 at this wavelength is directed at normal incidence onto a polished silicon wafer of thickness 0.5 mm.a. Assuming a top surface reflectance of 30..
What is the PIV required of the diode? A half-wave rectifier employing a 12-V-rms 60-Hz sine-wave source and no dc load is filtered using a polarized electrolytic capacitor having a small leakage current.
modify the Very Simple CPU to incorporate a new 8-bit register,R, and two new instructions. MVAC performs the transfer Râ†AC and has the instruction code 1110 XXXX; MOVR performs the operation ACâ†R and has the instruction code 1111 XXXX.
Find the transfer function and the difference equation for a 2nd -order FIR filter that has unity d.c. gain, but for which the given input x(k) produces zero forced response. (Your filter will have a "notch" at the given frequency, and H(1) =1.)
What is the value of RTH?
Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010
Bob enters a pizza shop and notices there are three different sizes of pizzas available. Sizes are given as the diameter of the pizza in inches. The cost of a pizza is based on the size. Bob would like to know which size of pizza
