A complex voltage waveform which has an rms value of 240 V contains 30% third harmonic and 10% fifth harmonic, both of the harmonics being initially in phase with each other. (a) Determine the rms value of the fundamental and each harmonic. (b) Write down an expression to represent the complex voltage waveform if the frequency of the fundamental is 31.83 Hz.

The springs effect is addressed below. As a relay some contacts are connected to, and move with, the armature. Other contacts are stationary and would make or break contacts as the armature moves.
1. Design a synchronous Mod-10 up counter from 1st principles nusing K-MAPS. Use Diagram 1(insert answer book) and also draw the final counter in your book. 2. Draw a MOD-10(5-bit) Johnson counter using D-bistables.
A magnetic material fills the half-space z 0) is free space. The per-meability of free space is mu_0 and the permeability of the magnetic material is 5 mu_0. The magnetic flux density in the magnetic material is B2= 10 ax+ 15 ay-20 az
A signal, m(t) which is bandlimited to 20 KHz, is going to be transmitted over a channel a) If the stepsize must be less than \(.002 m_{p}\) and the number of steps mut be a power of 2, calculate the minimum number of bits that satisfies this crit..
A phase modulation is used to transmit the signal s(t) = 10cos(20*pi*t) + 5sin(10*pi*t). kp = 3 rad/volts and fc = 20MHz a) What is the instantaneous frequency of the signal b) Write down the expression of the transmitted signal.
Find the poles and zeros of H(s) and plot them in the s-plane. Find then the corresponding impulse response h(t). Determine if the impulse response of this system is absolutely integrable so that the system is BIBO stable.
