One interesting item that I also reviewed along with the subwoofer was a nifty, outboard, electronic high-pass filter the company also sells.
Because the VTF-3 MK-3 has that variable low-pass adjustment range of 30-90 Hz, it can integrate to near perfection with any slope offerings available with the high-pass network.
The conventional filtering techniques: f-k, High-Pass and BandPass are applied in the frequency domain but in the case of Ground Roll amplitude stronger than reflection signals, f-k filters cause serious distortion of the signal (Karsh and Bayrak, 2004).
The analyses with f-k, High-Pass and the KL Filters gave the better results for the last one.
The scaling function and wavelet function correspond to a low-pass filter and a high-pass filter, respectively, and are called "quadrature mirror filters" in a signal processing context.
The raw cutting sound signals were processed by the digital high-pass filter (FIR, degree = 64, cutoff frequency [f.
By performing large-gain and high-pass
signal conditioning in a single stage in the analog domain, the AD8232 can accommodate electrode DC offsets while operating on a single supply voltage without sacrificing performance or signal quality.
Normally, you could do this by merely setting a typical surround processor or outboard crossover so that the main-channel speakers were high-pass filtered above a certain point and with the low bass going to a subwoofer.
I did hookup in such a way that the separately amplified Cantata woofers and my SVS 16-46PC subwoofer were handling the low bass as a team, with the Cantata woofers given additional low-pass filtering by the same crossover that was high-pass filtering the midrange drivers.
If the high-pass
filter for both of the mid-bass drivers is 80 Hz, then it only makes sense to have the low-pass frequency locked in to properly accommodate that roll-off.
Unlike traditional ear plugs currently used by concert-goers, event spectators and musicians that distort the sound by "muffling" the mid and high frequencies, Comply (TM) Foam Plugs use acoustic baffling and high-pass
filters to even out the sound blocking across the entire frequency spectrum.
Supports low-pass, high-pass
, notch/band-stop, band-pass, and all-pass phase shift/time delay filters to help ease system design.
