Design a 4-stage bi-directional serial-in serial-out shift register using 74ls76 j-k flip-flops and nand gates. structure your design so that the data is shifted on the leading edge of the clock. verity the 4-stage bi-directional serial-in serial-out shift register using multisim. use a clock frequency of 1 hz, and use switches to manually toggle the inputs of the shift register to shift bits into the device. use a digital oscilloscope to examine the output waveforms of the shift register.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
