For a bandpass filter specified as “s a p b p c s d ap e as f ”, the stopband edges were a and d, the passband edges were b and c, the attenuation in the passband was e and the attenuation in the stopbands was f. For a lowpass filter specified by “p a s b ap c as d“, the passband edge was a, the stopband edge was b, the attenuation in the passband was c and the attenuation in the stopbands was d.
