In some cases it may be necessary to use the functional block for an analogue or other circuit block.
If an item is bought in as a mixer, attenuator or so forth, it is not necessary to show its internal workings - in deed these may not be known.
In cases like these, or just to simplify a circuit, symbols for functional blocks may be used.
Like other circuit symbols, these blocks have been standardised so that anyone reading the circuit can understand them.
These analogue functional block circuit symbols have been defined in a number of specifications or standards including BS 3939. Some alternatives have also been given.
