I am trying to make a temperature warning system in LabVIEW.

given temperature T, I want a green light to turn on when temperature is less than 75 degrees. when the temperature is between 75 and 90 degrees, i want a yellow light to turn on. when the temperature is greater than 90 degrees, I want a red light indicator to turn on.

how would this case structure look like in LabVIEW?

Derive the small-signal model for the buck-boost converter. Then further derive Gvu(s) and Gvd(s).

a)In applying pull up and pull down principle, demonstrating all steps and in your own
understanding use Y = A +{ B × ( C +D ) } to DESIGN four input CMOS Static logic gate
.

b) In your own understanding in the field of electronics analyze the advantages of BJT
over MOSFET?

c ). In your level of understanding, explain the importance of biasing a transistor in a given
working electronic Circuit. Explain also the consequence when such transistor does not
biases properly

Explain how a shift register may be used to expand the output capabilities of a processor when only utilising a few pins
