(cid:863) A bode plot is a tool (in this case) for analysing a filter, and determining what effect the filter will have on different signals (will it kill them, or amplify them?). For this class, and other similar uses, it can be used for: Describing how a filter will need to behave / does behave. Making it easier to find the requirements of a filter. Finding out how a filter will interact with different signals. Finding out how the filter will react to a specific signal (sort of) In general, a bode plot describes (graphically) the response of any given system to a given signal. How much the system will amplify (or decrease) the signal. How much the system will delay the signal by.
