y[n + 2]- y[n +1]+ 0.5y[n] = 4x[n +1]+x[n]
a. Find the system's transfer functionb. Find the system's impulse responsec. Find its unit step response when the ICs are y[-2] = 2 and y[-1] = 1.... Be sure to identify the three parts of the solution: zero-input, transient zero-state, and steady-state zero-state.
A line has an inductance of1.25mH/km with an impedance angle of 70 degree , and a capacitance to neutral of 0.01mF/km. Calculate its reactance and series impedance per unit length at 50Hz. Calculate the line admittance per unit length
Sketch a Bode plot for the frequency response of a High-pass R-C filter where R=470ohms and C=0.047uF. Draw the circuit, calculate the actual cutoff frequency, and calculate the dB level at one-half the critical frequency and twice the critical fr..
Using Floating Point Unit and the switch statement Create an HLA program to perform the following: -Two data conversions (decimal,binary,hex) -Two measurement calculations (miles,feet,meters,inches) -Two logical operations(and,or,x-or)
A 35 kVA transformer supplies a load of 12 kW at a power factor of 0.45 lagging. Find the percentage of full load the transformer is carrying. If additional unity power factor loads are to be served with the same transformer,
A network has an input impedance of 120+100j Ω what is the capacitance that should be placed in parallel with the network to provide an input impadance with: a) Zero Reactance at w=1000 rad/s b) Zero Reactance at w=2000 rad/s
Many communication systems connecting computers employ a technique known as "packet transmission." In this type of system, a collection of binary digits (perhaps 1000 of them) are grouped together and transmitted as a "packet."
Assume A is the MSB and B is the LSB. The circuit produces an output of 1 if and only if the sum of the current 2-bit input and the previous 2-bit input is equal to 6. Design the circuit using as few D flip flops as possible. Draw the state diagra..
Two dc motors are compared. the first one is a 4hp dc motor which draws a current or 0.7A when the field is connected to a 150V source. the second, a 600 hp motor draws a field current of 5A when the field is connected to a 300V dc source.
A square of charge Q lies in the x-y plane with sides of length L, centered at the origin. A point P lies a distance z above the origin along the z-axis. Calculate the E-field at P. Put the final answer in terms of Q, not the charge density.
Indicate the magnitude and direction of the shear streses on the bottom of the block and the plate. If the force is removed suddenly and the block begins to slow, sketch the resulting speed versus time curve for the block.
the N-type P-type doping levels of a silicon p-n junction are nd=na= 5x10^16 cm^-3 caltulate the built in voltage Vbi a) at a room temperture b) at 300c c) at 700 c (ni= 1.10x1018 cm^-3) does a negative value for Vbi mean anything
Determine whether the system described by (1) y[n]=log(nx[n]), (2) y[n]=sqrt(n)*x[n+1], (3) y[n]=x[n-2]u[n], where a is an integer and |a|>1, is (i) memoryless; (ii) invertible; (iii) causal; (iv) stable; (v) time invariant; (vi) linear
