What is the low frequency magnitude of a filter ? There is a question in my textbook asking me to find this but l don't know what is it. Can someone please explain to me
Maybe it refers to the filter's gain on very low frequencies, where you can simulate the filter's capacitors with open-circuits. Also known as DC gain.

When it comes to filters "magnitude" refers to the gain(loss) with respect to some reference point. That reference point is usually the input, and the output level is compared to the input as a function of frequency.
