What would have to be altered in that circuit to increase the voltage gain?

What would have to be altered in this circuit to increase its overall voltage gain? The voltage divider would have to altered so as to send a smaller proportion of the output voltage to the inverting input.

What is the correct output condition for inverting comparator inverting comparator?

The basic configuration for the negative voltage comparator, also known as an inverting comparator circuit detects when the input signal, VIN is BELOW or more negative than the reference voltage, VREF producing an output at VOUT which is HIGH as shown.

Which is the non inverting comparator in this circuit?

Inverting terminal is kept at reference potential. In this case the reference voltage is zero. i.e. Vref = 0V. Figure below shows the Non-Inverting Comparator. The op-amp is in open loop configuration and hence its output is in saturation. The saturation level at the output may be positive or negative depending on the input signal.

When does a comparator change its output state?

Also at the reference point the state change occurs at the output when input signal crosses the reference voltage. Thus reference voltage is also called as threshold voltage at which the comparator is changing its output state.

What is the reference voltage of the non inverting terminal?

In this circuit input is applied to the non-inverting terminal of op-amp. Inverting terminal is kept at reference potential. In this case the reference voltage is zero. i.e. Vref = 0V. Figure below shows the Non-Inverting Comparator.

What are the transfer characteristics of an inverting zero crossing detector?

The transfer characteristics are shown in figure below. The reference voltage is zero here and hence the circuit is also called as inverting zero crossing detector. The reference voltage can be changed externally with the help of potential divider arrangement.
