A sinusoidal voltage of peak value 169.9 is applied to a load Z=16-j9.
a)What is the peak active power delivered to the load?
b) What is the value of the average active power delivered to the load?
We need to use asynchronous TDM and combine 50 digital sources. On average only 20% of the sources are active at any time. Each output slot carries 18 bits of data from each digital source. Also 8 extra bits are added to each frame for synchroniza..
Calculate the minimum value of Vd if the power flow through the converter is 5 kW (a) from the ac to the dc side and (b) from the dc to the ac side.
A 74x163 counter is hooked up with inputs ENP, ENT, and D always HIGH, inputs A, B, and C always LOW, input LD_L = (QA.QC)', and input CLR_L = (QB.QD)'. The CLK input is hooked up to a free-running clock signal.
How many turns are required for a circular loop of 100-mm radius to develop a peak emf of 10mV if the loop rotates 30r/s in the earth's magnetic field Take B = 60E-6T.
Describe what precautions you will take in designing the analog front end of the instrument before you perform the sampling for DSProcesing. Justify your claims by using engineering arguments.
A Si IMPATT diode is operated at 140 GHz with a dc bias of 15 V and an average biasing current 150 mA. (a) If the power conversion efficiency is 25% and the thermal resistance of the diode is 4OoCnV.
An input signal given by Vin(t)=5cos(500pi*t)+5cos(1000pi*t)+5cos(2000pi*t) is applied to a basic lowpass RC filter. R=318.3 ohms and C=1 microFarad. Find the expression for the output signal in terms of t and pi.
Apple A5 die size is 122mm^2 when fabricated in 45nm technology. Assume they purchase 300mm wafers at a foundry for $ 2.5K /wafer. Assume a yield of 70%. What is Apple's approximate die cost?
Calculate the percentage second harmonic distortion present in the output. Calculate the percentage error in the output voltage compared to its ideal value at the instant of time when t= 1/3200 seconds.
Determine the Laplace transform of f(t) = +5e^-4t + 12sin 3t. If the voltage across a 2 F capacitor is initially zero, what is the instantaneous power if the current is A?
