Explain how system-level specification and modeling languages are selected for performance evaluation of system-on-chip (SoC) blocked-based designs.

A single-phase transformer 5 kVA, operating at 50 Hz frequency has turns ratio of 20. The primary and the secondary winding resistances are 0.15 Ω and 0.025 Ω respectively, and the primary and secondary leakage reactances are 0.65 Ω and 0.15 Ω respectively. The magnetizing inductance and core loss resistance are 6 Ω and 1 Ω respectively.

i. Calculate the primary and secondary impedances referred to primary and sketch the APPROXIMATE equivalent circuit. (Note: please show all parameters in the circuit)

ii. Hence, by referring to primary equivalent circuit, determine the supply voltage and its phase angle if output terminal is connected to a load ZL= 14∠20° Ω and load voltage, V2 is 240∠0° Vrms.

determine the voltage regulation and efficiency when core loss is equal to 100 W.

Signals and systems

Consider the following discrete signal x[n] = sin(π n/32) (u[n]-u[n-33])

a) Using MATLAB only, Find the DFT using FFT algorithm,

b) Plot the signal x[n], spectrum |X(ω)|^2 , and phase of X(ω).

Hint: use L=512 for FFT.

Project Assignment

Construct the Y_bus matrix of a given power network by computer programming, preferably MATLAB. Note that the necessary data are available in the IEEE common data format; and as the working data, you can use the IEEE 14-bus system data.

Outline how the extraction of electronic system level characterization data is achieved in terms of collection, organization, integration and analysis for performance for field programmable gate arrays (FPGA)?

A normalized message signal has a bandwidth of W = 10 KHz and a power of
Pm= 0.75 . It is required to transmit this signal via a channel with an available bandwidth
of 80 KHz and attenuation of 50 dB. The channel noise is additive and white
with a power-spectral density of N0/2 = 10^(-10) watts/Hz. A frequency-modulation
scheme, with no pre-emphasis/de-emphasis filtering, has been proposed for this
purpose.
1. If it is desirable to have an SNR of at least 40 dB at the receiver output,
what is the minimum required transmitter power and the corresponding
modulation index?
2. If the minimum required SNR is increased to 60 dB, howwould your answer
change?
3. If in part 2, we are allowed to employ pre-emphasis/de-emphasis filters with
a time constant of τ = 75μsec, how would the answer to part 2 change?

In Microbots, When you press the red stop button of the teach pendant in the middle of the execution of a @STEP command, the Microbot stops immediately. Given that there are no sensors to independently determine the current position and orientation, how can you prepare for and recover from this event without having to recalibrate the robot manually to its home position?

Assume that no slippage occurs. Please include algorithm in pseudocode to explain the solution.

Gives the following four numbers:
a.01101010 b.11110001 c.10001000 d.00100010
then answer the questions:
(i) What's the decimal value of each signed binary number in the sign-magnitude
form?
(ii) What's the decimal value of each signed binary number in the 1’s complement
form?
(iii) What's the decimal value of each signed binary number in the 2’s complement
form?
(iv) Perform a + b in the 2’s complement form.
(v) Perform d – c in the 2’s complement form.
(vi) Multiply a by b in the 2’s complement form.

Question 3
a) A coil consist of 2000 turns of copper wire having a cross sectional area of 0.8mm2. The mean length per turn is 80 cm and the resistivity of copper is 0.02μΩ-m. Find the resistance of the coil and power absorbed by the coil when connected across 110V D.C supply. AN [8marks]
b) A circuit consist of four 100W lamps connected in parallel across a 230V supply. Inadvertently, a voltmeter has been connected in series with the lamps. The resistance of the voltmeter is 1500Ω and that of the lamps under the conditions stated is six times their value when burning normally. What will be the reading of the voltmeter?
