The following MATLAB command has been used to perform offline filteringy=filter([0.8 -0.8],[1 -0.3],x);
Where x and y are the input and output vectors, respectively. What is the transfer function of the filter?
A control system for positioning the head of a floppy disk drive has the closed-loop transfer function T(s)=11.1(s+18) / (s+20)(s^2+4s+10). Plot the poles and zeros of this system and discuss the dominance of the complex poles.
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
What would be the initial value of v c (t) when switch is closed and determine the time constants in both cases (switch is open, switch is closed).
A linear CW product detector local oscillator has a 500 Hz error while detecting an AM signal. What will the receiver's output sound like What if the receiver is listening to a DSB or SSB signal
Discuss how energy is stored in capacitors and inductors. Are the equations linear or non-linear How do you know? Discuss the concept of duality and why it applies to many fundament engineering concepts.
Design a load resistor (resistance rating and power rating) network to have the transformer operate at full load. Design a second network for half load. You may need to combine several resistors to get the desired value.
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
Design a vending machine controller. The machines sells coke and pepsi. The cost is 25 cents, accepting dimes and nickels. When a dime is inserted the input D is asserted. When a nickel is inserted the input N is asserted.
A 450 kW motor operating 73% Power factor lagging is connected to a 120V(rms), 60Hz line. (a) Sketch and label the power triangle for the motor. (b) Find the rms current into the motor.
Deer ticks can carry both Lyme disease (L) and human granulocytic ehrlichiosis (H). In a study of ticks in the Midwest, it was found that 16% carried L, 10% carried H and 25% that had either L or H carried both.
Addition of two numbers in IEEE 754 format A) a=3f200000, b=be600000 B) a=3f200000, b=ff800000 C) a=01100000, b=80e00000
A 345-kV, 3-phase transmission line delivers 100 MVA, 0.866 lagging, to a wye connected load. Calculate the following: a. The total real and reactive power delivered to the load. b. The real and reactive power per phase.
