Tracking/storage elements
The tracking/storage elements are storage elements for the parameterized input quantity. The outputs are linked to connectors.
Transfer of the input quantity is controlled via the RESET, TRACK and STORE functions:
RESET: When the controlling binector reaches log. "1", the output is set to 0.00% (y=0)
TRACK: When the controlling binector reaches log. "1", the output is set to the input value and then tracks it continuously (y=x). If the
TRACK signal switches from "1" to "0", the last value applied to the y output is "frozen"
STORE: With a "0" to "1" transition of the controlling binector signal, the output is permanently set to the current input value (y=x). This
value then remains stored
