Let the input be the sum of two sine waves: x(t) = A1sin(2πf1t) + A2sin(2πf2t). Assume the digital filter will pass both these frequencies with a gain of 1. This filter implements a linear phase response. What can you say about the output of the filter? That is, derive an equation describing the output as a function of time.
A hybrid communication system uses both AMSC and FM. The information signal a(t) is first AMSC modulated with the subcarrier frequency 1000 Hz. Then it passes through an FM modulator with the carrier frequency 10Mhz.
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..
assume filter is connected to a pure resistive load. The cutoff frequency is not to drop below 25krad/s. What is the smallest load resistor that can be connected across the output terminals of the filter.
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal) and should have a stability margin of 92%.
Determine the relative permittivity of the dielectric, the maximum and minimum electric field intensities in medium 1 and the electric field intensity in medium 2.
Modify the above VHDL code so that in addition to the 6 outputs listed above, the circuit outputs the largest and the smallest operands on the new outputs ‘largest' and ‘smallest'. Also output the sum, difference and product of the two operands A ..
What is Cramer's Rule and how to Find Two Variables by Cramer's Rule (need the answer Step by Step with Solved Examples
function [y,m] = averaging(x, n, N) where "y" is the output sequence, "m" is the corresponding index vector, "x" is the input sequences with index vector "n", and "N" is the order of the averaging filter.
a. Write an ARM assembly language instruction that uses the BIC instruction to clear bits 16-23 in R7 g. Show how you would schedule the three instructions MULT R2, R2,R1; ADD R2, R3, R2; and SUB R8, R9, R8 to reduce the chance of anRAW hazard.
Consider the function f which has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Write the canonical product-of-sums expression for f. Do not use the shorthand notation
Stock Z is a growth stock that will increase its dividend by 20 percent for the next two years and then maintain a constant 12 percent growth rate there after. What is the dividend yield for each of these four stocks?
A Whetstone bridge has a strain gage in the lower right leg with a 120 ohm nominal resistance. It is mounted on steel with a Modulus of Elasticity equal to 30x106. The other resistors are equal to 120 ohms.
