Given the binary sequence 1000000001. a. Use pseudoternary waveform to code it (the most recent preceding bit ‘0’ has positive voltage).
b. The long ‘0’s sequence will cause clocking problem. Also use scrambling techniques HDB3 to substitute four consecutive zeros (after first bit, the number of nonzero pulses is odd).

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
