Machine A was purchased three years ago for $10,000 and had an estimated market value of $1,700 at the end of its 10-year life. Annual operating costs are $1,350. The machine will perform satisfactorily for the next seven years.
Design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
A square wave signal with voltage levels 0 volts and 2.0 volt at a frequency of 1.00 MHz is multiplied by a sine wave at a frequency of 5.0 MHz
The solution to Power Factor, Two single-phase loads are connected in parallel across a 415 V, 50 Hz supply. One load is rated 130 kW at a power factor of 0.75
An amplifier with a power gain of 3dB is to be characterized. The test apparatus provides a SNR of 20dB at the input and measures a SNR of 15dB at the output. Find the amplifier's NF. Specifications for (2), (3), (4) and (5).
The lens-makers' equation applies to a lens immersed in a liquid if n in the equation is replaced by n2/n1. Here n2 refers to the index of refraction of the lens material and n1 is that of the medium surrounding the lens.
