Design a second-order band-pass IIR filter with center frequency of 450 Hz when the sampling frequency is 2,000 Hz. In order to ensure the filter stability, set the poles at 0.96 radial distant from the origin, and to eliminate the filter output delay, place two zeros at the origin.
The nickel- cadmium (nicad) battery is a secondary battery, meaning it can be recharged. it has the following reactions occuring during discharge: A nicad battery has .87 g of cadmium, which is the limiting reactant.
A current source of 12 cos 2000t A, a 200-ohm resistor, and a 0.2-H inductor are in parallel. Assume steady-state conditions exist. At t = 1 ms, find the power being absorbed by the (a) resistor; (b) inductor; (c) sinusoidal source.
he circuit is excited by a full-wave, ac/dc SCR converter. The ac voltage (input to the converter) is 120 V (rms), and the circuit resistance is 5 Ohm. At a trggering angle of 30 degrees, the load current is continous . Calculate the following
What is the function of the enable control input of a tri-state buffer If the output of two or more tri-state buffers is connected to each other, what is the restriction on enable control input lines What does happen when this restriction is viola..
Determine the distribution of the number of customers waiting in the queue.
Compute the unit-pulse response h[n] for the discrete-time system y[n+2]2y[n+1]+y[n]=x[n] (for n = 0, 1, 2, 3).
Find the system transfer function H(s) = Y(s)/X(s) if the input x(t) and the output y(t) of the system are related by the equation y(t) + 3y(t) = x(t) - x(tau)d tau. Assume y(0) = 0.
In the electronics business, mark-up is in the order of 100% to 130% at each level of middleman. Let's say that it is 100%. Let's further say that your product passes through three levels of middleman, that your product is produced in accordance
Identify how the existence of interest groups and political parties affect the public opinions of Texans. Is this affect beneficial or hinderances to the prinicipal of local control popular in Texas policy Why
A FIR filter is depicted in the figure below. Assume that the system is at rest and an input sequence is applied to the system. Determine the first seven samples of the system output Assume that the system is initially at rest. x(n)=u(n)+u(n-1)-2u..
A ideal transformer is rated at 4800/480 volt, at 75KVA. it is connected as a step down auto transformer. find the line and load voltages, turns ratio and total apparent, real and reactive power at full load and at 60% rated load at a power factor..
Let x(t) and y(t) be two real, periodic signals that are orthogonal to each other. Show that the power of the sum of the signals (i.e., x(t) + y(t)) is equal to the sum of the individual powers (i.e., Px + Py).
