Consider a receiver that consists (in the sequence) of the following components: (i) an antenna connector and feed line with an attenuation of 1.5 dB; a low-noise amplifier with a noise figure of 4 dB and a gain of 10 dB, and a unit gain mixer with a noise figure of 1 dB. What is the noise figure of the receiver?
Determine the coefficients p, q, and the determinant (delta) of the system: y1'=y1 + 10y2 Y'2=7y1 - 8y2 Based on these values, what is the type and stability of the critical point
Design and simulate a power supply that takes line voltage(120v) and produces a 15V output with less than .5% ripple voltage with the following specifications use either full wave or full bridge wave.
For a Wien-bridge oscillator Given R = 20Kohm and C = 10nF what is the frequency of oscillation Given a required frequency of oscillation of f = 3kHz and R = 5kohm, what should the value of C be
Write a function printBinary() that displays the number of bits used VB2010. Using 'sizeof()' if the user enters and int 17 the function should display 000000000000000000000000000010001.
A portion of the wave will reflect from the load and propagate back down the line to arrive at the input once again. Find the power that returns to the input and express this as a loss in decibels when compared to the original 10W input.
(1) In a lab experiment on parallel Resonance circuit with switch closed, What is the phase relationship between Ic and IL at Is minimum (2) Why is the source current , Is, minimum at a given frequency
In step four of this problem, how do you know in which direction to simplify the resistance for the thevenin resistance. (since you come up with a different answer depending on which direction you choose to simplify from)
A three-phase wye-delta transformer is rated 225-kV:24-kV, 400 MVA and has a single-phase equivalent series reactance of 6.08 ohms as referred to its high-voltage terminals. The transformer is supplying a load of 375 MVA
Calculate capacitor size, An electrical supply company charges its consumers a penalty if their reactive energy consumption (Kvar-hour)exceeds half their true energy consumption (Kilowatt-hour).
The length of a wire of a potentiometer is 100 cm, and the e.m.f. of its stand and cell is E volt. It is employed to measure the e.m.f. of a battery whose internal resistance is 0.5 ohm. If the balance point is obtained at l =3..
(d) Use the colon operator to create a matrix D by extracting the first through third columns of matrix A. (e) Create a matrix F by extracting the values in columns 2, 3, and 4 and combining them into a single column matrix. (f) Create a matrix G tha..
A simple voltmeter with a full-scale reading of 50(V) is required. Use a d'Arsonval movement with a rating of 20(mV) at 1 (mA). Calculate the value of the voltmeter resistor, Rv, required to achieve these design specifications.
