If a signal is single-ended, one side is at the common ground potential in the circuit, the other contains the signal. Signals are referenced to this common "signal" ground. In most circuits this is the only ground potential, but in some circuits separate grounds are used for different parts. In particular, in digital circuits the ground for the digital signals may be speparated from the ground for analog signals. Sometimes the power supply return is kept separate from signal ground, and sometimes the chassis and cabinets are connected to a speparate ground. At some point, however, these grounds are tied together.
If an amplifier or other component has a terminal for "signal" ground, that is what is used as the common for all incoming and outgoing signals. There may also be a separate chassis ground which can be used to connect to real earth ground (from the power plug). These cannot be used interchangeably.
