by frequency vs by a frequency

Both "by frequency" and "by a frequency" are correct, but they are used in different contexts. "By frequency" is used when referring to the rate at which something occurs or is repeated, while "by a frequency" is used when specifying a particular frequency among many. The choice between the two depends on the specific context in which they are used.
