Derive, by hand, the solution to steady state error for this unity feedback system with a PI controller. Compare to your MATLAB result. Enter the steady state error here.

Audio signals, band limited to 20kHz, are sampled and time-division multiplexed using PAM.What is the minimum frequency of the PAM pulses to enable the simultaneous transmission of10 audio signals?

1) What is Abstraction? What is the difference between Abstractions and mislead or alter important information? What is complexity and how do we deal with it. Please provide examples.

Calculate the wavelength of an electromagnetic wave operating at a frequency of 428MHZ.

On the circuit on Figure P2, transistor Q1 has a current gain BC, C2, and C3 can be assumed to be very large. You can also assume that the output resistance r.looking into the collector of Q1 is very large.100. Vcc = -Vee = 6 V. Capacitors 1. What type of transistor is Q1 on Figure P2? а.Find IR, Ic, IF, and Vce. Is Q1 operating in the active region? b. What is the operating point (Qpoint) of Q1? c.Compute gm and r. a.Draw the small signal equivalent circuit of the amplifier circuit on Figure P2. . Derive and compute the amplifier's voltage gain A, Derive and compute the input resistance RIN and the output resistance RoUT of the amplifier.C.

If a PV module has module and azimuth angle of 30° and 130° respectively, calculate the direct and global irradiation on it. (Points 10)

2. Using PSpice (or alternate), obtain the output characteristics (ic versus vce ) for an non 2N3904 BJT. The base-emitter junction is forward biased with a DC current source and the collector-base junction is reversed biased by a DC voltage source connected between the collector and emitter. Use the DC analysis and set up the DC sweep. The dialog box should be opened and for the main Sweep variable type VCE , the linear sweep is set from 0 to 10 V in increments of 0.01 V. The Nested Seep button is clicked to open its dialog box, and for the Nested Sweep variable type iB , use a linear seep from 0 to 60m A in increment of 10 m A. In Probe add the trance IC(Q1) and obtain the BJT output characteristics(you are supposed to get the BJT's curves).

An AM modulation process uses a carrier frequency of 100kHz. Suppose that the modulated signal is used to modulate a 200kHz carrier. Find the frequencies of the demodulation process that can be used to recover the original signal.

Using D Flip-Flops with any other logical gates, draw a 5-bit shift register that can either load a sequence of 5 bits in parallel or produce serial output.

A laser pointer emits red light having peak wave length of 750 nm. Calculate the energy of the photons it is emitting.
