a. Find the power spectral density of the periodic function x(t) = cos(t) + sin(t).
b. Compute the average power contained in this function directly and then by making use of the power spectral density to find the average power.
Describe the filter that yields an AM signal for g (t). Give the necessary filter type and the frequencies of interest.
If an NMOS or CMOS transmission gate is turned off (an open switch), discuss why the output voltage is, in general, not stable.
a) If m1 and m2 are minterms of n variables, prove that m1 OR m2 = m1 XOR m2 b) Prove that any switching function can be written as the exclusive-OR sum of the products where each product does not contain a complemented literal.
calculate the potential required so that the plate does not move (the weight is balanced by the electrostatic force).
Functional Area Review Your group's task is to study the role of a functional area within a corporate environment. "my functional area is supply chain management" You will need to interview professionals working in a corporate environment and condu..
DeSign a Miller integrator with a time constant of 0.1 s and an mput reSistance of 100 kfl. A dc voltage of - I volt IS applied at the input at time 0, at which moment tI" = -10 V. How long does it take the output to reach 0 V') + I 0 V
A 3-phase delta/star transformer is supplies 6000 V on delta connected side. The terminal voltage on the secondary side when supplying full load at 0.8 lagging power factor is 415 V. The equivalent resistance and reactance drops for the transforme..
The cylindrical coaxial cable with the cross section shown below, has inner and outer radii of 5mm and 15mm respectively. The dielectric parameters are; er=2, signma=5*10^(-10) S/m and Ur=1.
What is maximum load current IL that can be drawn from the Zener regulator in Fig. if it is to maintain a regulated output? What is the minimum value of RI that can be used and still have a regulated output voltage?
The Ebers-Moll model was one of the first mathematical models used to describe the characteristics of the bipolar transistor. Show that the npn Transport Model equations can be transformed into the Ebers-Moll equations below.
Letthe predetection SNR be sufficiently high to ensure that the PLL does not lose lock. Using MATLAB and the histogram routine, plot the estimate of the pdf at the VCO output. Comment on the results.
