Abstract
A coin validation circuit and method of operation thereof, including a memory having stored therein a data entry for each acceptable denomination, a validation control circuit, preferably including a microprocessor, operatively connected to the memory, an analysis circuit, preferably a ringing circuit, operatively connected to the validation control circuit and operable to produce output signals, and a monitor circuit operatively connected to the analysis circuit to respond to a particular predetermined output signal characteristic, the validation control circuit operable during a coin validation operation with respect to any one of the acceptable denominations to retrieve from the memory a predetermined data entry, to produce a conditioning signal corresponding to the retrieved predetermined data entry to effect a pre-conditioning of the analysis circuit in accordance therewith, and to thereafter produce a coin analysis initiation signal, the analysis circuit responsive to such initiation signal to produce an output signal the characteristics of which are dependent, in part, both upon the particular pre-condition of the analysis circuit and upon any coin in the coin analysis field of the analysis circuit, the output signal produced in response to such initiation signal having associated therewith the particular predetermined output signal characteristic if a coin of the particular acceptable denomination whose associated data entry was retrieved from memory and utilized to pre-condition the analysis circuit is in the coin analysis field of the analysis circuit, regardless of the denomination of the coin submitted to examination or the particular acceptable denomination with respect to which the coin validation operation is conducted.
