The transfer characteristics of a noninverting buffer in the ecl family are described by the following equations:
v0 = {0, vi < _0.85 v
2.6 [1 -1 /{1 + exp(vi - 1)/vt)}], 0.85v < _ vi < _1.2v
2.6v, vi > _ 1.2v
1. calculate the logic leveles and noise margins (vol, vol(max), voh, voh(min), vil, vih, nml, nmh). use vt = 26mv.
note: since gain is positive in the transition regions for noninverting circuits, use slope = 1 at logic transitions.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
