a)
From the given circuit VNT2 and VIT1 are constant.
VNT2 =
VIT1 =
By the principle of Comparators, when VNT
VIT , then Vout = +VS ; when VIT
VNT , then Vout = -VS.
For t < 1.25, VIT1 > VNT1
VNT1 = Vin.
Vout1
becomes -Vs ,i.e. Vout1 = 0V.
Vout =0V(Ground),
irrespective of the voltage Vout2 , for t < 1.25.
For 1.25 < t < 2.5, VNT1 > VIT1 ,
Vout1
becomes +Vs ,i.e. Vout1 = +5V.
And Vout2 is already +5V,
VNT2 > VIT2 for 0 < t < 2.5.
Overall Vout = +5V for 1.25 < t < 2.5.
For 2.5 < t < 7.5, VIT2 > VNT2 , Vout2 = Vout =0V.
For 7.5 < t < 8.75, Vout1 = Vout2 = Vout = +5V
And for 8.75 < t < 10, Vout1 =0V,
Vout = 0V.
b)
Since in the circuit, the cathode of the LED is connected to the output of the Comparator,
The
LED will turn on for Vout = 0V, and turn off for Vout = +5V.
LED will be ON for 0 < t < 1.25 , 2.5 < t < 7.5, and
8.75 < t < 10.

The circuit below is a temperature range indicator using a Window Comparator circuit. Discuss when you would use this type of analog circuit and when you would use a microcontroller based circuit like that of Lab 4 shown below. A window comparator usually employs 2 comparators with one output indicating the input is somewhere between two limits. In these examples, a third comparator is...
