Typical applications use only three of the five conductors: a ground wire (pin 2), and a balanced pair of conductors (pins 4 and 5) that carry the MIDI signal as an electric current. [87] [74]: 41 This connector configuration can only carry messages in one direction, so a second cable is necessary for two-way communication.
Maestro sostituto or maestro collaboratore: musicians who act as répétiteurs and assistant conductors during performances. Maestro concertatore , the keyboard continuo player, who prepares singers and leads rehearsals.
The roles of a conductor vary a great deal between different conducting positions and different ensembles. In some cases, a conductor will also be the musical director of the symphony, choosing the program for the entire season, including concerts by guest conductors, concerto soloists, pop concerts, and so on.
The difference between the revenue from selling a unit of electricity and the cost of the fuel used to make it. spark-gap transmitter A former type of radio transmitter that generated radio frequency current by exciting resonance of a tuned system with an electric spark, used almost entirely for transmission of Morse code. spectrum analyzer
The ampacity of a conductor, that is, the amount of current it can carry, is related to its electrical resistance: a lower-resistance conductor can carry a larger value of current. The resistance, in turn, is determined by the material the conductor is made from (as described above) and the conductor's size.
Acclaimed maestro Leonard Bernstein was a guest conductor in Cincinnati on four occasions. And each time he caused a stir. Before Netflix’s ‘Maestro,’ Leonard Bernstein was ‘triple-threat ...
Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
The pair of conductors can be wires in a twisted-pair or ribbon cable or traces on a printed circuit board. Electrically, the two conductors carry voltage signals which are equal in magnitude, but of opposite polarity. The receiving circuit responds to the difference between the two signals, which results in a signal with a magnitude twice as ...
