Hi. I have some basic questions on inverters. If the logic symbol has a bubble on the output, that means the output is opposite of the input. So a high input will result in a low output and a low input will result in a high output. Is this the same if the bubble in located on the input side of the logic symbol instead of the output side? Also, what if there is a bubble on both the input and output side of the inverter logic symbol? Thanks!
