A velocity receiver is a sensor that responds to velocity rather than absolute position.
For example, dynamic microphones are velocity receivers.
Likewise, many electronic keyboards used for music are velocity sensitive, and may be said to possess a velocity receiver in each key. Most of these function by measuring the time difference between switch closures at two different positions along the travel of each key.
Famous quotes containing the word receiver:
“Flattery corrupts both the receiver and the giver.”
—Edmund Burke (1729–1797)
