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?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
