Abstract:
An apparatus for providing a source signal at a predetermined frequency, the apparatus comprising:(a) a signal generating device; said signal generating device providing a periodic signal; (b) a signal synthesizing device; said signal synthesizing device being connected with said signal generating device; said signal synthesizing device including an accumulating device; said accumulating device having a maximum bit capacity; said accumulating device recurrently accumulating bits to said maximum bit capacity and returning to a starting bit count in a bit accumulating period; said recurrent accumulating being effected by a periodic incremental quantum change in said bits being accumulated in response to at least one repeating event contained in said periodic signal; said signal synthesizing device generating said source signal based upon said bit accumulating period; (c) a processor device connected with said signal synthesizing device; said processor device issuing a correction signal to said signal synthesizing device to control said incremental quantum change; said processor device having a stored correlation base for correlation between a parameter of ambient temperature and said correction signal; (d) a temperature sensing device for sensing said parameter of ambient temperature; said temperature sensing device being connected with said processor device; said temperature sensing device and said processor device cooperating to employ said parameter of ambient temperature with said correlation base to select an appropriate said correction signal to drive said signal synthesizing device toward generating said source signal at said predetermined frequency; said correlation base being a correlation table relating said parameter of ambient temperature change with said correction signal.
