How would I synthesize this logic function using one or more 74x138 or 74x139 binary decoders and NAND gates? F = Sum A,B,C,D (0,2,10,12)
A 138-kV, three-phase short transmission line has a per-phase impedance of (2+j4) ohms. If the line supplies a 25-MW load at 0.8 power factor lagging, calculate (a) the efficiency and (b) the sending-end voltage and power factor.
A three-phase, wye-connected, 220-V, 10-hp, 60-Hz, six-pole induction motor has the following parameters in ohms per phase referred to the stator: R1 = 0.294; R2 = 0.144; Xn = 0.503, X12 = 0.209;XM = 13.25.
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
We are required to create a digital clock for the upcoming project. The class has been very disorgainzed and hard to follow, thus I've had a hard time keeping up with what's actually going on and don't quite understand all the material.
Consider the causal LTI system with system function H(s)=Y(s)/X(s)=1/(s+2)^2 If the input is x(t)=sin(2t) for t>0, find an approximate expression for the response y(t) that is valid for large t.
