At any time, the user can input a pause display command, resulting in a first recorded portion of the time sequential signal to be recorded.

A signal correlator (42) and error detector (45) are coupled to receive and correlate a direct sequence, spread spectrum signal to be tracked and prompt and E-L reference code output signals from the reference code generator (41).

In an acoustic signal encoding apparatus (100), a tone/noise judgment block (110) judges whether an entered acoustic time sequential signal is a tone or a noise.

Each iteration is correlated with a sequential signal from the sequence of recorded signals comprising the information code of an element in the game set which is selected by a player as a bet.

An adaptive delay lock loop for tracking a direct sequence, spread spectrum signal is disclosed which includes a reference code generator (41) having adjustable weighted early and late taps.
