The transfer characteristics of a noninverting buffer in the ecl family are described by the following equatio:

0, v s 0.85 v v, 2.601 1/11 exp((v 1)/vd)], 0.85 v s vi s 1.2v 2.6v vi e 1.2 v

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.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
