A four-section binomial matching transformer is to be used to match a 12.5 load to a 50 line at a center frequency of 1 GHz.
(a) Design the matching transformer, and compute the bandwidth for m = 0.05. Use CAD to plot the input reflection coefficient versus frequency.
(b) Lay out the microstrip implementation of this circuit on an FR4 substrate having
The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move..
Give a brief explanation of the concept of a priority encoder. Using this, what would be the binary output for a 10-input priority encoder when inputs 7 and 5 are activated What is the binary output (active-high) Active-low
A 20kW, 250V, self-excited dc shunt generator is driven at its rated speed of 1200rpm and it is delivering rated power at rated terminal voltage. Its armature-circuit resistance is 0.15-ohm, and the field current is 2 A.
A buck converter is supplied by a DC source of 48V. It produces an output voltage of 18V across a 10? load resistor. Assume that the capacitor is large enough so that the output voltage is kept constant. Determine the duty cycle D.
An ECG lead is oriented such that its electrodes are placed onthe body in positions that pick up an electromyogram from the chestmuscles as well as the electrocardiogram. Design a circuit thatseparates these two signals as well as possible, and discu..
n the conduction band of a semiconductor, it has a lower valley at the center of the Bril- louin zone, and six upper valleys at the zone boundary along [100]. If the effective mass for the lower valley is 0.1m0 and that for the upper valleys
A single-phase transformer has 480 turns on the primary and 90 turns on the secondary. The mean length of the flux path in the core is 1.8 m and the joints are equivalent to an airgap of 0.1 mm. The value of the magnetic field strength for 1.1 T i..
Assume that this whole system is linear, so that, if the pressure on a sprinkler is halved, the area covered (as well as the flow rate) will be halved. This is true until the pressure is reduced below 20psi, at which it does not work at all.
Approximately how many harmonics terms are required in the Fourier Series of a bipolar square wave with 50% duty cycle and amplitude A to represent 99% of its power?
An electron describes periodic oscillations in the direction of the axis "z" with amplitude of 1 nm (nano meters) around a ring, if the ring has a total charge of 100e with a radius of 50 nm (nano meters) . Determine load osilacion and maximum spe..
When a capacitor is connected to a DC source its voltage rises from20 V to 36 V in 4μs with an average current of 0.6 A. Determine the value of capacitance.
