Webb12 sep. 2008 · Abstract: A novel elliptic-function low-pass filter (LPF) is presented, which consists of a dumb-bell-shaped defected ground structure (DB-DGS), a spiral-shaped defected ground structure (SP-DGS) and a broadened microstrip line. The DB-DGS provides the required wideband attenuation in stopband, while the SP-DGS provides steep … WebbA sharp roll-off is also handy for removing rumble from a drum break or vinyl sample when you’re using a high-pass filter. It’s common to see terms like 12dB and 24dB used here (or -12dB and -24dB). You may also see this number combined with the filter type, so LP24 for a low-pass filter and BP12 for band-pass. canceled desc user canceled the push
