An earth station receive antenna has a sky component temperature of20 K, a ground component temperature of 15 K . What is the total antenna noise temperature [K]?
Because A-B=A+(-B), the subtraction of signed numbers can be accomplished by adding the complement. Subtract each of the following pairs of 5-bit binary numbers by adding the complement of the subtrahend to the minuend.
Calculate the torsional spring stiffness constant for a steel shaft 0.5" in diameter and 2.5 ft long.
Assume a 20 V voltage drop occurs across an element from terminal 2 to terminal 1 and that a current of 4A enters terminal 2. (1) Based on passive network convention, state whether the element is absorbing or delivering power.
Three single-phase two-winding transformers, each rated 25 MVA, 34.5/13.8 kV, are connected to form a three-phase bank. Balance positive-sequence voltages are applied the high voltage terminals, and a balanced, resistive Y load connected
Design an experiment that allows frequencies between 300-3300 Hz to pass with a 14 dB gain. At f = 10 KHz and f = 100 Hz, the gain should be -16 dB. Use a cascaded design consisting of first and second order Butterworth sections.
A load impedance ZL = 100 + j80 is to be matched to a 75 ohm line using a single shunt-stub tuner. Find two designs using open-circuited stubs. Include both smith chart and analytical analysis.
The equation y[n] - p y[n-1] = x[n] can be used to describe thevalue y[n] of a new investment by setting p = 1 + r/100 where r is the interest rate per period, expressed inpercent.
trace how the electrons and holes move through the device under the two different biasing conditions. Explain how these three devices work in terms ofIn a study conducted at the National Institute of Mental Health,
the cut-off frequencies of a series resonant circuit are 5400 Hz and 6000Hz. a. find the bandwidth of the circuitb. If Qs is 9.5 , find the resonant frequenciy of the circuit c. if the resistance of thecircuit is 2 ohms, find the value of Xl andXc at..
With respect to sinusoidal signals, explain the difference between the way we normally define "amplitude" and the "amplitude" measurement on an oscilloscope. Also, How does the amplitude setting on a function generator relate to these
Derive the state space equation of a DC motor with: 1)supply voltage and load torque as inputs and 2)armature current, angular speed as outputs.
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
