a) Explain Systematic Errors and Random Errors with suitable a case study for each error. Briefly comment on your answer based on your explanation.
b) A computer engineer created a program in which the input signals are accepted from the sensors in the form of denary numbers and the output device requires the signal to be in binary form, but the processor works only based on the signals in the form of octal number. If the input is given to be 5613.90625, then what will be the binary number for the output signal? Give a brief comment based on your answer.
c) An electrical engineer while checking the electric circuit of an electronic device connects an Alternating voltage of 240 V, 50Hz across an impedance of (60 - j 100) Ω. Determine the resistance, the capacitance, the magnitude of the impedance and its phase angle and the current flowing. Give a short comment on your answer.
d) A complex signal encoder sends signals through the radio waves in the form of complex equation (x - j2y) + ( y - j3x) = 2 + j3. The decoder on the other end decodes the complex signal to reveal the message. Solve the above complex equation to decode the signal. Briefly give a comment on your answer.
The voltage across an element is v(t) = 5e-7t V. The current entering the positive terminal of the element is i(t) = 1e-6t A. Find the energy absorbed by the element in 0.038 s starting from t = 0.

Find the system transfer function of a causal LSI system whose impulse response is given byh[n] = (-0.5)^n-1 sin[0.5(n-2)]u[n-2] and express the result in positive powers of z. Hint: The transfer function is just the z-transform of impulse respon..
average velocity of v meters/second. If the concentration of free electrons is 10^{29} electrons per cubic meter and if they are uniformly dispersed throughout the wire, then what is the average velocity of an electron
A n-type Si wafer is doped with Nd=1e15/cm^3, find the level of acceptor doping we need to convert the wafer from n-type to p-type, with a target hole density p=5e15/cm^3. also ni = 1e10/cm^3
Suppose the RTD of (108.1 Ohms) has a dissipation constant of 25mW/°C and is used in a circuit that puts 8 mA through the sensor. If the RTD (108.1 Ohms) is placed in a bath at 100°C, what resistance will the RTD have
