In sound reproduction , the meter, whether peak or not, is usually meant to correspond to the perceived loudness of a particular signal. In modern audio equipment, peak meters are usually made up of a series of LED s small lights that are placed in a vertical or horizontal bar and lit up sequentially as the signal increases. There are many variations on how this is implemented. They typically have ranges of green, yellow, and red, to indicate when a signal is starting to overload . The term peak is used to denote the meter s ability, regardless of the type of visual display, to indicate the highest output level at any instant. A peakmeter can also be implemented with a classic moving needle device such as those on older analog equipment similar in appearance in some ways to a pressure gauge on a bicycle pump , or by other means. Older equipment used actual moving parts instead of lights to indicate the audio level. Because of the mass of the moving parts and mechanics, the response time of these older meters could have been anywhere from a few millisecond s to a second or more. Thus, the meter might not ever accurately reflect the signal at every instant of time, but the constantly changing level, combined with the slower response time, led to more of an average indication. By comparison, peak type metering is designed to respond so quickly that the meter display reacts ... ear works much more like an average meter than a peakmeter.

An S meter signal strength meter is an indicator often provided on communications receiver s, such as amateur radio receivers or shortwave broadcast receivers. The scale markings are derived from a subjective system of reporting signal strength from S1 to S9 as part of the RST code . The term S unit can be used to refer to the amount of signal strength required to move an S meter indication from one marking to the next.

A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of Electrical impedance impedance measuring device, though it is still in use among radio amateurs.

Loughlin ref http www.hp.com hpinfo abouthp histnfacts museum earlyinstruments 0010 Boonton Q Meter Type 160 A, 1946 HP Virtual Museum ref . A Q meter measures Q, the quality factor of a circuit, which expresses how much energy is dissipated per cycle in a non ideal reactive circuit math Q 2 pi times frac mbox Peak Energy Stored mbox Energy dissipated per cycle . , math This expression applies to an RF and microwave filter , bandpass LC filter , or any resonator. It also can be applied to an inductor or capacitor at a chosen frequency. For inductors math Q frac X L R frac omega L R math Where math X L math is the reactance of the inductor, math L math is the inductance, math omega math is the angular frequency and math R math is the resistance of the inductor. The resistance math R math represents the loss in the inductor, mainly due to the resistance of the wire. For LC band pass circuits and filters math Q frac F BW math Where math F math is the resonant frequency center frequency and math BW math is the filter bandwidth. In a band pass filter using an RLC circuit LC resonant circuit , when the loss resistance of the inductor increases, its Q is reduced, and so the bandwidth of the filter is increased. In a coaxial cavity filter, there are no inductors and capacitors, but the cavity has an equivalent LC model with losses resistance and the Q factor can be applied as well.

A TDS Meter indicates the Total dissolved solids Total Dissolved Solids TDS of a solution , i.e. the concentration of dissolved solids in it. Since dissolved ion ionized solids such as salt s and mineral s increase the Conductivity electrolytic conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that. Dissolved organic solids such as sugar and microscopic solid particles such as colloids, do not significantly affect the conductivity of a solution so a TDS meter does not include them in its reading. Units of TDS A TDS meter typically displays the TDS in parts per million ppm . For example, a TDS reading of 1 ppm would indicate there is 1 milligram of dissolved solids in each kilogram of water.

merge Time signature discuss Talk Additive meter Merger proposal date April 2010 In music, additive meter refers to a pattern of Beat music beats that subdivide into smaller, irregular groups. This is opposed to divisive or multiplicative rhythms or meters, which are produced by multiplying some integer unit into regular groupings forming beats of equal length London 2001 . Such meters are sometimes called imperfect , in contradistinction to perfect meters in which the Bar music bar is first divided into equal units Read 1964, Page number date December 2010 . Additive meter is common in Music of Eastern Europe Eastern European musics , and contemporary compositions attempting to emulate such a sound. For example, a time signature like 9 8 is normally subdivided as 3 3 3, or nine eighth notes with three to a beat. However, the composer or Conducting conductor may specify an additive meter for passages of music where it is more natural to conduct with a different pattern. Hence, a meter like 9 8 may instead be subdivided as 2 3 2 2 for musical effect most commonly such an additive meter is used when Accent music accented notes or Syncopation syncopated patterns do not match up with the normal subdivision. Flamenco music, for instance, is full of additive meter, particularly in rhythms of 10 3 3 2 2 . Alfred Reed s Armenian Dances Part I contains a movement written in the nonstandard time signature of 5 8, which can be conducted as either 2 3 or 3 2 depending on which is more musically natural.
