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.
