In the previous example, we want to avoid aliasing by oversampling by a factor or two, digitally filtering, then "decimating" by a factor of two down to the 44.1kHz rate; that is, we will sample at 88.2 kHz. To do the filtering, we use a 100-tap FIR filter. Assuming each digital processing step is a single operation, how many MegaFLOPs (million floating point operations per second) will we need to perform to accomplish this, assuming there are no parallel operations? Remember, we're working in stereo. The previous example: We want to produce "CD quality" digitized audio: 44.1 kHz, 16-bit stereo audio.

(a) What is the 3 dB bandwidth limit for this digitization rate?
(b) What is the total byte rate (kb/sec) for this digitization?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
