I routinely talk about a signal having the value zero. This comes from more than fifty years of engineering experience. However, some claim that zero is not a signal value; it means there is no signal at all. This is one of those disputes where engineers, physicists, and users of everyday language are talking past… [Read More]
Counts vs DNs
When engineers of a my advancing years talk about raw ADC outputs, they tend to call them counts. That word choice is not entirely a matter of habit or stubbornness. It reflects how those systems were actually experienced and debugged at the time. In early systems, the output of an analog to digital converter was… [Read More]
