    Nyquist, Bode Plot and Root Locus

    A) Analyse the closed loop stability of the system with open loop transfer function {see attachment} i)Make a sketch of the Bode diagram and hence the full Nyquist diagram, showing all relavent details ii) If the system is unstable, state the number of closed loop right hand plane poles and comment on how you might stabili

    Root Locus of a System

    Draw the root locus for the system with the open loop transfer function given in the attachment that is connected to a negative feedback loop and confirm the relevant break-away points are at s = 0 and s = -1. See the attached file.

    Determining sequence of output waveforms

    I have come across this question in a mock exam paper and although I believe it is quite simple, I am having problems deciding how to complete this question. Could you please answer this question and explain your results so that I can understand how to answer such questions in the future. Please see the attachment

    Design a Highpass FIR Filter Using Kaiser Window

    Design a highpass FIR filter using Kaiser window design technique. This problem is from the textbook 'Digital Signal Processing using MatLab' by Ingle/Proakis. Design a highpass FIR filter using Kaiser window design technique. The specifications are: Stopband edge: 0.4pi;, As = 60dB Passband edge: 0.6pi;, Rp = 0.5dB W

    Problem on how to find the voltage gain of the amplifier

    A power amplifier when driven by a current source of 5mA rms and a source resistance of 8k, delivers 12.5W signal power to an 8k load resistance. Find peak to peak value of the output voltage. If the input voltage to the amplifier shows 5V rms, determine the voltage gain of the amplifier. Show how you arrived at your answer.

    Determining Angular Frequency from Period

    A sinusoidal voltage has a maximum value of 100V, and the value is 10V at t=0. The period is T=1ms. Determine the angular frequency, w, in rad/sec. a) 3.14 b) 6.28 c) 3142 d) 6283

    FINFET---a type of MOSFET

    The question is below. Please include where you find the resource to answer this question. Thanks. As the gate length of MOSFET transistor shrinks to nanometer scale, the operation of MOSFET is limited by fundamental physical process. One of the most severe limitation is the inability to reach complete cut-off mode for nano

    Bode Plots and Harmonic Response

    Please see attachment. a) Draw the Bode plot (on semi-logarithmic graph paper) of the transfer function. see attached aii) From the Bode plot, what would the approximate harmonic response of the above system to an input, u(t)=sin(2t)? Confirm your answer by simple calculation.

    Numerical Integration and Euler's Formula

    For this question, please leave out the proof. Assume the formula is already known. Also, instead of assuming a unit step of U(t) = 1(t), change the question to a sinusoidal input of U(t) = sin(2t). Please solve this question and explain all the steps in detail.

    LC Circuit with constant current source and 2 switches

    Hi, I know you do not do homework assignments but I am studying for a test tomorrow and these are practice tests with no answers and so I really need to learn how to do them. Could you please help me understand the entire problem (again, this is not a homework problem, just practice)? See the attachment.

    Systems and Simulation: Bode Plots

    For a "notch" filter with transfer function P(s) = [s^2 + 0.1s + 1]/[s^2 + 10.1s +1] i) Sketch the asymptotic Bode magnitude plot on a piece of logarithmic graph paper ii) Correct your asymptotic sketch at 0.5, 1 and 2 times the value of each corner frequency, and iii) Make a reasonable sketch of the Bode phase plot on a sepa

    Could you please simulate the dynamic behaviour of the system using matlab and simulink for the mass - spring system? Please refer to the attachment.

    Finding appropriate source for the electrical load

    Have four circuits. One takes 9Vdc, two 5Vdc, and last one takes 12Vdc. Have variable transformer for source. How do I calculate or choose the voltage needed to run all four circuits with out blowing them all up, and at the same time run each circuit by themselves or two at a time or three, etc. How do I know how much curren

    Theveninization of a Transistor Circuit

    Find Icq and Vceq for the circuit when Beta=100. I put the 60k and 30 k resisters in parallel and then did a thevenin equivalence on the parallel combination resistance and the 20k ohm resistor. Then, I did kvl around the b-e loop and got icq=.021ma and vce=.39v. Did I do the thevinin equivalence correctly? See the attach

    Complimentary Output Rectifier

    In the complementary output rectifier, If Vs=26*sin 2*pi*60*t Volts, sketch the output waveforms vo+ and vo- versus time, assuming Vgamma=.6V for each diode. I don't understand the graphic questions. Will there ever be a time when the voltage goes negative? because it looks like a FWR. Thanks
