# Determine by the order of transfer function what kind of filter

How can I determine by looking at the following tranfer function, that is this the transfer function of a band-pass filter:

$$\frac{1}{as^3+bs^2+cs+1}$$

• That is not a bandpass filter, and the order has something to do with the polynomial in the denominator. – a concerned citizen Apr 17 '18 at 6:13
