Derive a state diagram for a Finite State Machine(FSM) that has an input w and an output z. The machine has to generate z = 1 when the privious four values of w were 1001 or 1111; otherwise, z = 0. Overlapping input patterns are allowed.
An example of a desired behavior is: w : 010111100110011111 z : 000000100100010011
A transmission line of char. Impedance 100ohm is used to match a 50ohm section to a 200 ohm section. if the matching is to be done both at 429MHz and 1GHz the length of the transmission line can be approx?.
A power amplifier has a gain of 15db and an input level of 2 volts. Assumming that the input and output impedance are the same. What is the voltage level at the amplifier output.
A square wave has a max value of 22 volts, a min value of -46 volts, and a frequency of 44 Hz. Note that it is not centered around the t-axis. what is its rms voltage?
A small buck converter has 24 V input and 12 V output. The transistor has Rds(on) - 0.1 Ohm. The diode is modelled as a 1.0 V drop. Each device has junction to ambient Rtheta(ja) = 40 K/W and Tjunction
Assume that an additional inductance can be inserted in series with the load. Also assume that the converter has no freewheeling diodes. Calculate the added inductance that leads to a conduction period of 180 degrees when alpha = 30 degrees.
Calculate the probability of finding an electron at the bottom edge of the conduction band. Also calculate the probability of not finding an electron at the top edge of the valance band.
A 150 MVA, 24 kV, 123% three-phase synchronous generator supplies a large network. The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage.
Design and model a car battery charger using PSpice. Suppose that the source is a commercial circuit of 240V AC at 60Hz. The battery to recharge is 12V DC.
Derive the dynamic model and average value circuit of a buck converter assuming the ESRs of the inductor and capacitor are not equal to zero.
The power factor of a load connected to a 120-V 60-Hz source is raised from 0.866 lagging to 0.966 leading by connecting a 110.5-F capacitor in parallel with the load. Determine the load current I1 and the circuit current IT
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.
Find the transfer function of a second-order system that yields a 10% overshoot and a settling time (Ts) of 1.5s, plus tell the nature of the system
