Determine the quantizing levels, in terms of σ, so that the entropy at the output of a quantizer is maximized. Assume that there are six quantizing levels and that the quantizer is a zero-mean Gaussian process as in the previous problem.
find the reactive vars which the compensation equipment must supply to maintain the voltage profile (a)when the line supplies load of 50 Mva at 0.85 p.f lagging (B) when the line is open circuited at the recieving end.
Calculate the line current required for a 30-kW three-phase motor having a power factor of 0.85 lagging if it is connected to a balanced source with a line voltage of 440 V.
find the MIN permissible SAG for a span of 225 m using a copper conductor with 1.2 cm diameter and allowing a MAX conductor tension of 2200 kg/cm^2 . The horizontal wind pressure is 6 g/cm^2 and specific gravity of copper is 8.9
If inductive load has a 2ohm resistance and 2microhenry inductance in series with a 120V/60Hz source and a capacitor is connected parallel to the entire load so no reactive power is being delivered by the source what is the capacitance value.
It is required to design a full-wave rectifier using a center tapped rectifier to provide an output voltage of 10 v. Find the required number of turns ration of the transformer. Assume that a conducting diode has a voltage drop of 0.7v. The ac lin..
For any lossless reciprocal three-port network, one port (say port 3) can be terminated in a reactance so that the other two ports (say ports 1 and 2) are decoupled (no power flow from port 1 to port 2, or from port 2 to port 1).
Write a program which uses 8 DIP switches on LAB PRO Board as 8 different speeds for motor. Each switch will run the dc motor at certain speed.
Determine the Polar form of the Impedance for the three components when they are Connected in series circuit and when they are connected in a parallel circuit. Determine it the final impedance is inductive or capacitive. Given: VPP = 400V, IRMS = ..
Choose a microcontroller for a particular application - Design circuits incorporating microcontrollers plus any additional hardware to control a particular application.
A source X produces symbols A, B, C, D, and E with probabilities 0.5, 0.25, 0.125, 0.0625 and 0.0625 (a) Find the information content of X. (b) Give a fixed length code for X. Compute its efficiency. (c) Derive a Huffman code for X
An electric heater is added to a room. If the heater has an internal resistance of 10 Ω and if energy costs 8 cents per kilowatt-hour, how much will it cost to continuously run the heater per 30-day month? Assume the voltage is 120 V.
