What is the difference between a class method and an instance method? Create a Line class using the coefficients a, b and c of the equation ax + by + c = 0 that represents the line as the class fields. Enforce the class invariant that either a or b is non-zero and c is either 0 or 1.
For each of the following functions find the values of S & Wn (omega n) and characterize nature of response (overdamped,underdamped,critical damped,etc) a) G(s)= 225/ s^2 +30s+225 b) G(s)= 625/ s^2 +625
A binary waveform of 53000 bits/sec is converted into an 8192 level waveform that is passed through a channel with a raised cosine-rolloff filter characteristic. The channel has a conditioned (equalized) phase response out to 4.0 kHz.
(a) if there is no current in the loop, what is the magnetic flux through the coil (b) When the current in the coil is 3.8 A in certain direction, the net flux through the coil is found to vanish. What is the inductance of the coil.
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
A 3.3 uH inductor is connected to a current source. The current of the source is changing according to time as 8.6 * t A. What is the voltage drop across this inductor (UNIT:mV)
Through a three-phase transmission line, a three phase symmetrical load is supplied from a power system bus. The parameters per phase of the transmission line are: R=5 ohms, X=70 ohms, B=9*10^-4 ohms.
A balanced three-phase 60 Hz source supplies power to a balanced-connected inductive load. The line voltage is 440 V, the line current is 8.2 A, and the power delivered to the load is 5 kW.
(1) If you have a transformer that is not in a circuit, how can you tell/determine what the ratio is (2) How do you tell if a diode is forward or bias. How much voltage is assumed dropped across a forward biased silicon diode. Reversed biased sili..
let X(s) be the Laplace Transform of signals that are bounded (i.e. the poles of X(s) are on the left-hand s-plane). Find lim [as t goes to infinity)] y(t). Determine if the system is BIBO stable. If not, determine what makes the system unstable.
Design both inverters with an on voltage of 0.7v., and a DC operating point of Vin = 0.8v., Vout =2.5v. Compare the inverters AC transfer curve and their rise and fall times. Use a load capacitance of 10pF.
A pn junction for which the breakdown voltage is 10 V has a maximum safe power dissipation of 0.5 W. a) What continuous current in the breakdown region will raise the dissipation to half the rated value
