The transfer characteristics of a noninverting buffer in the ECL family are described by the following equation: 0, V; s 0.85 v V0 = 2.6[ 1 - 1 / { 1 + exp((V, - 1 ) / Vr)}], 0.85 V < V, < 1 .2 V 2.6 V, V; 1 . 2 V Calculate the logic levels and noise margins. Use V7 = 26 mV. Note: Since gain is positive in the transition regions for noninverting circuits, use slope = 1 at logic transition

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?
