11Chebyshev filter — Linear analog electronic filters Network synthesis filters Butterworth filter Chebyshev filter Elliptic (Cauer) filter Bessel filter Gaussian filter Optimum L (Legendre) filter Linkwitz Riley filter …
12Linear phase — is a property of a filter, where the phase response of the filter is a linear function of frequency, excluding the possibility of wraps at pmpi. In a causal system, perfect linear phase can be achieved with a discrete time FIR filter.Since a… …
13Channel (communications) — Old telephone wires are a challenging communications channel for modern digital communications. In telecommunications and computer networking, a communication channel, or channel, refers either to a physical transmission medium such as a wire, or …
14Network synthesis filters — Network synthesis is a method of designing signal processing filters. It has produced several important classes of filter including the Butterworth filter, the Chebyshev filter and the Elliptic filter. It was originally intended to be applied to… …
15Power trio — The power trio is a rock and roll band format popularized in the 1960s. The traditional power trio has a lineup of guitar, bass and drums, leaving out the rhythm guitar or keyboard that are used in other rock music to fill out the sound with… …
16Bass reflex — A Bass reflex system (also known as a ported, vented box or reflex port) is a type of loudspeaker enclosure that uses the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies as compared to a… …
17Peak programme meter — A typical British quasi PPM. Each division between 1 and 7 is exactly four decibels and 6 is the intended maximum level. A peak programme meter (PPM) is an instrument used in professional audio for indicating the level of an audio signal. There… …
18Very minimum-shift keying — VMSK, for Very Minimum Shift Keying modulation, is one of several digital modulation methods claimed to send high speed digital data through very low bandwidth (or narrowband) channels. A typical claim is a data rate of 6 Mbit/s in a bandwidth of …
19Index of optics articles — Optics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.[1] Optics usually describes the behavior of visible,… …
20Butterworth filter — The Butterworth filter is one type of electronic filter design. It is designed to have a frequency response which is as flat as mathematically possible in the passband. Another name for them is maximally flat magnitude filters.The Butterworth… …
