In a test of a printed circuit board using a random test pattern, an array of 10 bits is equally likely to be 0 or 1. Assume the bits are independent.(a) What is the probability that all bits are 1s?(b) What is the probability that all bits are 0s?(c) What is the probability that exactly five bits are 1s and five bits are 0s?
A short distance system is composed of two identical transmission lines with an amplifier between them. A 1 mW signal is transmitted at one end and is received at the other end with an SNR of 22 dB.
Given a 1-phase 50 kVA 12.47 kV pf = 0.8 lagging static load a. Modeling the load as constant complex power, determine the correct value for S and I. b. Modeling the load as constant complex impedance, determine the correct value for Z and I.
Efficiency of MOSFET circuit provide in datasheets of any product is measured at transient state of my output node or staedy state?
A 300 kW, 6600 V, 8-pole, 50 Hz, three-phase, Y-connected, non-salient pole (i.e., cylindrical rotor) synchronous motor has the following parameters: Xs = 72 ohm /phase at 50 Hz, R =10 ohm/phase for operation near base speed, and Efo = 3200 V/phase..
An altimeter can measure 0-100m; using a signal conditioner, this high position is distributed over a voltage range of 0-5V. If an ADC covering the same voltage range outputs 1000 0000, what is the distance measured
For much of the last century, the annual growth rate of energy utilization in the world was 3.5% per year. At present, the rate of global energy usage is approximately 15 TW. When considering only coal, oil, and gas.
A three phase load draws 100kW at a poer factor of 0.7 laggaing from a 220V line to line. In parallel with this load is a three phase capacitor bank which draws 60kVAR. Find the total line current and the resultant power factor.
A coil having 1000 turns is wrapped on ferromagnetic core constructed of sheet steel. The core has a cross-sectional area of 0.0009 m^2 and an average flux path of 30.0 cm. The core also has a length of 2 mm. The flux density in the core and airga..
A double-convex lens is to be made of a transparent material with an index of refraction of 1.3. One surface is to have twice the radius of curvature of the other and the focal length is to be 72 mm.
