Hello students for question number seven when three inverters are connected in series, inverters are connected in series the overall switching point or the threshold voltage the overall switching point or the threshold voltage of the combined circuit will be different from the individual switching points of each inverter of the combined circuit will be different from individual switching points of each inverter.

In this case if three inverters are connected in series then the this will be the input and the output of first inverter is connected as input of second inverter and the output of second inverter is connected as input of third inverter and so on.

So in this case this creates a cumulative effect on the overall switching point so this means that the switching point switching point in series connection series connection is slower than slower than the individual connection individual connection.

For the second case we have to show that switching point of the inverter in series is dominated by the switching point of the first inverter this is question number eight.

So when inverters are connected in series like this the inverters are connected in series the overall switching point is primarily influenced by the switching point of the first inverter in the series that is this is i1.

So here let us consider we are connecting n inverters in this case i will have drawn four inverters in series and the output of each inverter is connected as input of the next inverter here the input voltage to the first inverter is v in and the output voltage of the last inverter is v out.

Here the voltage transfer characteristics of an inverter can be represented by plot of v out versus v in...
