A directional coupler has the scattering matrix given below. Find the return loss, coupling factor, directivity, and insertion loss. Assume that the ports are terminated in matched loads.
Create a new device symbol for the Full Adder and save it and create a new device symbol for the 4-bit cascaded adder.
The resistance of a copper wire at 30oCis 50Ω. if the temperature coefficient of copperat 0oC is 0.00427, what is the resistance at100oC
What is the minimum number of bits required to represent each of the following decimal numbers: 10, 1000, 100,000, and 1,000,000?
When calculating the bending stress of a rectangular plate, one must use the section modulus about the neutral axis of the plate. This axis is at the center of the plate where there is neither tension nor compression.
Design a 4-bit synchronous up/down counter using T flip-flops. The circuit has one input up' /down such that input 0 means count up and input 1 means count down. up' is "up" with a bar over it
Make a user interface (using matlab) for amplitude modulation and demodulation without using the ammod and demmod function. The program should ask the user the 3 types of message signal (Square ,sinc,sinusoidal, triangle, sawtooth)
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
Include a discussion of the importance of electrical isolation when interfacing microcontrollers to higher voltage inductive circuits (motors). Include detail of how electrical isolation can be achieved to protect the microcontroller and motor.
A synchronous motor exited by 5 kV source has a synchronous reactance of 5 ohm .The motor is running without any mechanical load(the output real power is zero). Ignore all losses and calculate thr equavelent field voltage Ef that delivers 3 M VAr ..
if the analog signal to be quatized is a sinusoidal wave form x(t)=9.5sin(2000*pi*t), and if the bipolar quatizere uses 6 bits - what are the number of quantization levels - quantization step size or resolution, delta, assuming the signal range
A hot-air balloon is rising upward with a constant speed of 3.86 m/s. When the balloon is 9.27 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground
