1. Find the velocity with which the group of two frequencies 2400 MHz and 2500 MHz travels in a parallel-plate waveguide of dimension a = 2.5 cm and having a perfect dielectric of
2. For a narrow-band amplitude modulated signal having the carrier frequency 5000 MHz propagating in an air dielectric parallel-plate waveguide of dimension a = 5cm, find the velocity with which the modulation envelope travels.
The voltage and current at the terminals of an ideal element are 0, for t _ (minus equal) 0s. V(t) = 100(1-e^(-300t) V, i(t) = 15e^(-400t) mA. Find the maximun power absorbed by the element by the element at t = 10ms
1- what is meant by plug and ply devices what are the bus protocols that support plug and play devices 2- what is hot attachment and detachment what are the bus protocols that support hot attachment and detachment
A stream of air at 80 °F and 1.2 atm absolute flowing at a rate of 200 ft3/h is blown through ducts that pass through the interior of a large industrial motor. The air emerges at 500 °F. Calculate the rate at which the air is removing heat generat..
Consider a Schottky diode at T=300 K that is formed with Pt qφM=5.3ev 'work function' on n-type silicon.knowing that qX for silicon =4.05ev (a) find the barrier height. (b) Calculate the saturation current.
Design by direct implementation the electronic circuits for equations as the following logic equations using any real 1, 2, or 3 input logic gates. Assume all signals are high true (positive logic) and do not simplify the equations.
A certain transmission line is 10 meters long. Measurements indicate that the total inductance of the cable is 16 H. Standing wave measurements indicate that the voltage reflection coefficient at the load is 0.5 + j0 when a 75 ohm resistor
what is the maximum bandwidth of this network, in bytes/s.
Subtraction can be performed easily if the operands arein the 10's complement (radix complement) representation. Inthis representation,the sign digit is 0 for a positive number and 9for a negative number.
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal) and should have a stability margin of 92%.
How many toggle switches would be required?
Find an expression for vO in terms of v1 and v2.- Design a suitable circuit that realizes the block diagram using only one OP AMP.
Design the combinational logic circuit for an elevator controller such that the option to go up or down by only one floor is disabled. Assume that the building the elevator is in has 4 floors. Your inputs are the current floor and the next request..
