a circuit consists of three elements in series. a source delivers 90 watts and one of the passive elements absorbs 20 watts. how much power does the third element absorb.
The output power of the digital transmitter is 0 dBm and the link has a constant attenuation of 50.0 dB. At the input to the receiver, the equivalent AWGN noise power is – 70 dBm. Assume implementation margin is 0 dB when calculating BER in ..
Suppose a data array has 30 numbers sorted from low to high already, where no two numbers are equal. We need to search whether any of the two randomly given key numbers, key1 and key2 is in the array. If yes, then find out the position index(es) f..
A cellular operator using the FDMA technique is allocated a total spectrum of 25 MHz. The system has a channel bandwidth of 60 kHz. It also uses a guard band of 20 kHz. Compute the number of channels that can be simultaneously supported in this wi..
Calculate the de Broglie wavelength, for: (a) An electron with kinetic energy of (a) 1.0 eV, and (ii) 100 eV. (b) A proton with kinetic energy of 1.0 eV. (c) A singly ionized tungsten atom with k in.
Write a C-Program that tells whether or not there are repeated cards amoung a 2-d array[4][13]. It returns "true" if it does. The program needs a function to determine whether or not it has repeated cards.
How can you make a low-pass filter with proper cut-off frequency to remove noise from a voice transmission using frequency spectrum What frequency cutoff would you use in that
An induction motor has an output or shaft power of 30 kW at 86% efficiency. For this operatingcondition, stator copper loss = rotor copper loss = core loss = mechanical rotational losses. Determine the slip.
Knowledge about Circuit Analysis, A 5.1K resistor is connected between the cathode of a 6.2V zener diode and a 12V power supply
Consider points P(2,4,3) and Q(1,-5,2) in three dimensional space: Find the position of vectors r1 and r2 for P and Q in terms of unit vectors i,j,k Determine graphically and analytically the resultant of these position vectors Hint: resultant vector..
For a unity feedback control system, the forward path transfer function is: G(s) = 20/(s^2 + 14s +50) a. Determine the steady-state error for a unit step input. b. Find the steady-state error for a unit ramp input using the Final Value Theorem.
a) Design a circuit with a single opamp to realize V0=V1-4V2, where V1 and V2 are two input voltages. b) Select the resistor values so that no more than .25W is dissipated in any resistor when the input voltages are no larger than 10V
