Is there an easy or straightforward way to analyze a frequency response plot/filter profile of a digital filter and determine it's architecture (number of taps, FIR vs IIR, decimation rate, coefficients, etc)

For example, what information do i have about the filter and it's implementation by looking these plots (these are two different filters) ?
