If a single stage amplifier is having an open loop voltage gain of 80, input resistance of 800 -ohm and output resistance of 200 -ohm, what will be the available signal voltage across a 50 -ohm load connected at the output of a cascaded amplifier made out of two such single stage amplifiers that is driven by a signal source having a source resistance of 600 -ohm and an open circuit signal voltage of 15 mV
A permanent magnet dc motor has two poles and a simplex lap winding of 18 loops and 3 turns per loop. The armature radius is 4 cm and the armature length is 15 cm. The flux density under the poles is 0.74 T.
Your program should be efficient in the use of memory and computational complexity.
A constellation diagram has two points located at (3,0) and (-3,0) on the I(in-phase)-Q(quadrature phase) plane. Find the value of peak amplitude and the type of modulation this diagram represents.
A 100 hp, 16 pole, 460V, three phase, 60hz induction motor has a slip of 2.4 percent when running at rated conditions. Determine (a) synchronous speed; (b) rotor speed (c) rotor frequency.
A quartz crystal microbalance (QCM) was employed in a vacuum deposition process, where a thin film of aluminum was grown over a p-Si wafer. The oscillator frequency at the start of the process was 10.0050 MHz.
For a transfer function with a pair of complex zeros located on the j (omega)-axis, what happens to the frequency response as the frequency applied to the system approaches the value at which the zeros are located
Help with problem in Control signal processing class, Consider the unity-feedback control system whose open-loop transfer function is
Identify five controls that require the operator to do two destict actions in order to activate the control? EXAMPLE depressing the clutch on a car so that the ignition key will start the car.
where ω0 is a constant, and Y, θ are statistically independent random variables. Assume that Y has a mean value of 3 and a variance of 9, and that θ is uniformly distributed from -π to π. Find the mean and mean-square value of the process.
The SV curve can be used to understand the impact of constant power factor shunt compensation support. In this case, the receiving end is injected with a specific amount of reactive power so that the receiving end maintains a constant load power f..
1. What happens to both resolution and full-scale output when the reference voltage on a DAC is increased by 20% a. resolution gets better by 20%, output goes down by 20% b. resolution gets worse by 20%, output goes up by 20%
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31mV/mm with +/-2cm maximum core displacement.
