A pure inductance of 120 mH is connected in parallel with a 25 μF capacitor and the network is connected to a 100 V, 50 Hz supply. Determine (a) the branch currents, (b) the supply current and its phase angle, (c) the circuit impedance, and (d) th..
Rewrite the MATLAB simulation of Computer Example 4.3 for the case of an absolute-value type of nonlinearity. Is the spectral line at the bit rate stronger or weaker than for the square-law type of nonlinearity?
A walker's cassette tape player uses four AA batteries in series to provide 6 V to the player circuit. The four alkaline battery cells store a total of 200 watt-seconds of energy. If the cassette player is drawing a constant 10 mA from the battery..
A series-tuned antenna circuit consists of a variable capacitor (40 pF to 360 pF) and a 240-µH antenna coil which has a dc resistance of 12 Ω.
Gaussian random variable W is known to have P[W>4] = 1/2. Based on this information, (a) sketch its possible PDF. (b) Now also assume that Var[W] is very small. Refine your sketch in the first part taking into account this new information.
Write a function called Balloon that will accept a single variable named S. The function should replace S with the square of S and repeat this process until S is either greater than 10^15 or less than 10^-15.
A system is described by the differential equation ty'(t)-8y(t)=x(t). Classify the system as to linearity, time-invariance and stability. A system is described by the equation y(t)= \(\int_{t/3}^{-\infty}\)x( \(\lambda\)) d.
