Synchronous
In hardware, it is an event that occurs in a fixed time
relationship to another event. In software, it refers to a function
that begins an operation and returns to the calling program only
when the operation is complete.
Throughput rate
The maximum repetitive rate at which data conversion system
can operate with a specified accuracy. It is determined by
summing the various times required for each part of the system
and then by taking the inverse of this time.
Timer
The timer allows the adaptation of program processes between
processor and peripheral devices. It usually contains from each
other independent counters and can be programmed for several
operation types over a control word register.
Trigger Internal
trigger:
A software generated event that starts an operation.
External trigger:
An analog or digital hardware event from an external source
that starts an operation.
Digital trigger:
An event that occurs at a user-selected point on a digital input
signal. The polarity and sensitivity of the digital trigger can
often be programmed.
TTL
= transistor-transistor-logic
A popular logic circuit family that uses multiple-emitter
transistors.
