In the event of an interrupt being initiated it immediately stores the contents of the working register in the temporary register Wtemp. This is because the working register may be used during the ISR and hence its contents changed.

Use 7 comparators inputting into the priority- encoder, one comparator inputting into the overflow indicator, 8 resistor voltage divider and a 3 bit output.
VLS= 2.3-0.7 = 1.6V
Input impedance =hfeRL=50 X 8= 400 ohms
Use a resistor divider network to provide positive DC bias
Use a push pull power amplifier which will reduce the effect of distortion but still produce crossover distortion
V1=12-7.5=4.5V
VL( approx) = VZ(1 + RF/R1), Max Value VL=7.5(1+1/3) = 9.98V ( approx 10V)
10V 7.5V
VS increases to 13V. Voltage across resistor increases but voltage across zener remains at 7.5V ie output voltage remains unchanged.
The dummy gauge is included to compensate for any changes in ambient temperature conditions.

VA = ( 12/318.06 +340) X340 = 6.20V
VB = (12/680)X340 = 6V

Vout = +0.2 X 50 = =10v
The thyristor must be Forward Biased
A positive gate pulse of sufficient voltage must be applied.

VR= 24 -2 = 22V
R = VR/Ig = 22/60mA = 367ohms
The de-coupling capacitors remove any unwanted DC from the input of the amplifier .

Gain on each channel is a max when the variable resistor are at minimum value ie = 0 ohms
Max gain on channel 1 =10, 100K/R1
Max gain on Channel 2 =100K/R2
