Hello,

Please forgive what may seem a simple and naive query, but could someone clarify the terminology used to desicribe what seems to be the same thing.

I often read articles including the use of, and see advertised, Signal Generators, Audio Generators, Frequency Generators and Function Generators and then combinations of all of these, i.e Audio Frequency Generators, etc. Is there any real or even subtle difference between these or are they just one and the same?

Many thanks,

Richard
