1. A unity feedback control system has an open-loop transfer function given by Eq. (1), Design in detail a lag compensator so that the phase margin of the compensated system is 40o and the steady state error to ramp input is less than or equal to 0.2. Verify your design in MATLAB by obtaining the phase margin of the compensated system using Bode command.
G(s) = k/s(s+ 2s)
2. A type 2 unity feedback system has an open-loop transfer function given by Eq.2. Use MATLAB to design a lead compensator to meet the following specifications:
- Settling time < 2 seconds. - Peak overshoot to step input < 25%
G(s)H(s) = k/s2(s+1.5)

a) A personal computer with a monitor and keyboardrequires 60 W at 110V (rms). Calculate the rms value of the currentcarrried by its power cord. b) A laser printer for the personal computer in (a) is ratedat 80W at 110V (rms).
For a 32 bit CMOS 5 volt microprocessor that has a 32 bit address bus and a separate 32 bit data bus, and the processor has a 1 nS rise time and 0.5 nH of ground inductance on a board made from glass epoxy material.
What is the maximum message bandwith for which the system operates satisfactorily? Determine the output signal to quantizing noise ratio when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
Calculate the built-in voltage of a junction in which the p and n regions are doped equally with 10^16 atoms/cm3. Assume ni =.5x10^10/cm^3. With the terminals left open, what is the width of the depletion region
A full-wave silicon rectifier is used with a power transformer to generate the DC output voltage for a low current application. Assuming the storage capacitors are sufficient to eliminate power supply ripple
Looking at this pattern from left (MSB) to right (LSB), when you see a ‘1' the pulse should be 'ON' for 0.5 seconds. If you see a ‘0', the pulse should be ‘ON' for 1.5 seconds. In either case, the ‘OFF' time should be 2.0 seconds after each ‘ON' t..
