  -Asynchronous arbiters:An important form of arbiter is used in asynchronous circuits, to select the order of access to a shared resource among asynchronous requests. Its function is to prevent two operations from occurring at once when they should not...
  
   helps order signals in asynchronous circuit
  Asynchronous circuit
  An asynchronous circuit is a circuit in which the parts are largely autonomous. They are not governed by a clock circuit or global clock signal, but instead need only wait for the signals that indicate completion of instructions and operations. These signals are specified by simple data transfer...
  
  s. There are also electronic digital circuits called synchronizers that attempt to perform arbitration in one clock cycle. Synchronizers, unlike arbiters, are prone to failure. (See metastability in electronics

  , whenever there is signal transfer between two systems operating at different frequencies or same frequency with different phases, synchronizer block is used as an interface so that signal from transmitter block is reliably interpreted by the receiver. The block usually uses metastable hardened flops offering single or double latency delays at the output. This block ensures that there is no metastability

  Synchronizer (film editing)
  A film synchronizer is a device used in the editing phase of filmmaking.Film synchronizers generally have 1 to 8 "gang", or slots through which film can be threaded. Each gang consists of a group of large diameter sprockets on a common shaft. A rotating knob on the front, which moves the threaded...
