1. List the types of heat pumps available by combinations of heat source and heat sink.
2. Why is a heat pump called a heat pump
3. How is the refrigeration cycle reversed in a heat pump?
Discuss how the solution for the electromagnetic field given by (4.52) corresponds to that of a uniform plane wave.
When a forward bias is applied across a junction is the increased current flow due to movement of the Fermi level closer to the band edge or to lowering of the potential barrier. If you want to increase the space charge width on the n side of a p,n..
What is the smallest sampling rate that will enable exact reconstruction of the useful signal if we do not perform any filtering on x(t) before sampling?
In natural-convection problems, the variation of density due to the temperature difference ?T creates an important buoyancy term in the momentum equation.
An amplifier has an input resistance of 100 Ω, an output resistance of 10 Ω, and a short-circuit current gain of 500. Draw the voltage amplifier model for the amplifier, including numerical values for all parameters. Repeat for the transresistance..
Given the configuration of Exercise 2.3. Calculate the gradient in cylindrical coordinates. Use the direct approach or the transformation from Cartesian to cylindrical coordinates.
Display the raw IR sensor input in the decimal point LED to aid in debugging and alignment.
design a 7-tap band-pass FIR filter with linear phase response. The lower cutoff frequency is 2,500 Hz, and upper cutoff frequency is 4000 Hz. The sampling frequency is 10,000 Hz. What is the filter impulse response
Consider a square house 40 ft on a side, 10 ft high, with a flat roof on top and walls/roof that is 8 inches thick. The thermal conductivity for an un-insulated wall or roof is 1.6 W/Km, while with fiberglass insulation its 0.04 W/Km.
Measurments taken of a square-wave signal using a frequency-selective voltmeter(called a spectrum analyzer) show its spectrum to contain adjacent components(spectral lines) at 98KHz and 126 KHz of amplitudes 63 mV and 49 mV
A flux density of 1.8 T exists in an air gap of effective csa 11 cm2. Calculate the value of the flux.
With regard to assembly language and the HCS12: What is the instruction to initialize the SP register Why do we initialize that register What is the reason we initialize it with the value $4000 for this microcontroller
