What is Fvtool in Matlab?
fvtool( rcfilter ) plots the magnitude response of the specified filter. fvtool( rcfilter , options ) plots the response that is specified by options . For example, to plot the impulse response of the specified filter, set options to 'impulse' .
What is magnitude response of a filter?
The magnitude response of filters can be characterized in terms of the frequency bands the filter will pass or reject. In Fig. 4.9 the ideal magnitude responses of the four most frequently used filter types are illustrated as a function of ω in radians per second.
