Why binary and not ternary computing?

Question

Isn\'t a three state object immedately capable of holding more information and handling larger values? I know that processors currently use massive nets of XOR gates and th

Answer 1

If we use 3 states, then the main problem arising due to this are

1. If we use unipolar signal then the noise margin will reduce, hence increasing the bit error rate.
2. For unipolar signal to keep the noise margin constant we have to increase the power supply and hence the power consumption will increase.
3. If we use bipolar signal then the total swing of the signal will increase thereby increasing the losses.
4. Extra layer in multilayer PCB will have to be added to account for negative swing in the bipolar signals.
