A tank containing 6000L of water drains out in 30 min. The volume V of water in the tank after t min of draining isV=6000(1-t/30)2. Find the instantaneous time rate of change of V after 15 min draining.
Design a circuit that provides a voltage gain of + 3. Draw the circuit schematic identifying supply voltages and show your work on component selection.
The time t required to test a computer memory unit is directly proportional to the square of the number n of memory cells in the unit. For particular type of unit, n= 6400 for t= 25.0s. Find the instantaneous rate of change t with respect to n for..
suppose that atransmitter sends power into a transmit antenna whose gain is +4bBi. The receiver some distance away receives a powe of -50dBm when operating with a receive antenna whose gain is -3dBi.
Binary data is transmitted through an Additive White Gaussian Noise (AWGN) channel with SNR=3.5 dB and bandwidth B. Channel coding is used to ensure reliable communications. Then: i. What is the maximum bit rate that can be transmitted
A compact disc (CD) records audio signals digitally by usingPCM. Assume that the audio signal bandwidth equals15kHz. a) If theNyquist samples are uniformly quantized into L = 65536 levels andthen binary-coded
A voltage divder is required to produce a 5.5V output from 12V source. If one of the resistor values is 1.0k, what value is required for the second resistor so that the voltage across the 1.0k resistor is 5.5V
Given coaxial cable with an inner conductor with radius a and anouter conducrot with radius b, find B forρ>b when the inner and outer currents are +100[mA] and-90[mA], respectively, and both conductors are centered along thez-axis.
Let a 4x inverter have transistors four times as wide as those of aunit inverter. If a unit inverter has three units of inputcapacitance and parasidic delay of pinv, what is the input capacitance of a 4x inverter
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
if a 1mA movement has an internal resistance of 43 ohms, calculate the shunt resistance required to increase its range to 50mA and also 300mA.
Compute the Transfer Equation, The questions are for the equation: y"(t) + 6y'(t) + 34y(t) = 2x'(t) + 11x(t)
