Consider the signalx(t) =sin(0.5t) / 0.5t(a) Find the Fourier transform X(Ω) of x(t).(b) Is x(t) band limited? If so, find its maximum frequency Ωmax.(c) Suppose that Ts = 2π. How does Ωs relate to the Nyquist frequency 2Ωmax? Explain.(d) What is the sampled signal x(nTs) equal to? Carefully plot it and explain if x(t) can be reconstructed.
A special case of the NON-inverting amplifier has Rf = 0.0 ohms. That is, the op amp output is connected directly ("short circuit") to the inverting input and Ri is removed entirely (i.e., Ri = infinite ohms; "open circuit").
a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the expressions obtained above for x[z] are identical.
However, for short-time operation, a delta connection can be used at the nominal wye voltage. Find the ratio between the power delivered to the same motor in the wye and delta connections.
A 115/28 V transformer has 56 turns on its low voltage side. How many turns does it have on its high voltage side what is its turns ratio when it is used as a step-down transformer
Compute the complex conjugate of each of the follwoing expressions: (a) -1; (b) -j/5
determine the voltage drop across the 20 Ohm resistor with respect to the 48 V source. I'm having difficulty understanding why the voltage comes out to a negative 12 V, then to a negative 8 V.
A calibrated RTD with alpha = 0. 0041 / degree C, R = 306. 5 ohm at 20 degree C, and PD = 30 mW / degree C will be used to measure a critical reaction temperature. Temperature must be measured between 50 degree and 100 degree C.
A network has an input impedance of 120+100j ohm. what is the capacitance that should be placed in parallel with the network to provide an input impadance with a magnitude of 100O at w=1000 rad/s
Write an assembly-language program to add $40 to each element of list1 and store it to the corresponding element of list2. Use a loop. ORG $2000 LIST1 DC.W $21, $442, 3, 4, 5
Implement switching function of 4 variables H(A,B,C,D)= AB'+BC+A'CD using a 4 to 1 Multiplexer and any number of 2 to 1 multiplexer. One can select any 2 variables (for example, AB or CD) as select inputs of one 4 to 1 multiplexer.
calculate the convolution (x1[x]*x2[k]) for the following pairs of sequences: a-) x1[k]=u[k+3]-u[k-2] and x2[k]=u[k+5]-u[k-4] b-) x1[k]=0.5^k u[k] and x2[k]=cos Pi*k u[-k]
The total current in a semiconductor is constant and is composed of electron drift current and hole diffusion current. The electron concentration is constant and is equal to 10^17 cm^-3. The hole concentration is given by p(x)
