Abstract
A signal generator is disclosed. The signal generator includes a variable frequency selector that is configured to provide a variable frequency for generation of a variable frequency signal. The signal generator also includes a periodic signal generator. The periodic signal generator is used to generate a periodic signal. The periodic signal generator has an input receiving the variable frequency signal and an output providing the periodic signal. The periodic signal has a frequency approximately the same as the variable frequency selection. The periodic signal generator stores a table of values associated with a reference periodic signal, each stored value corresponding to a discrete time in the reference periodic signal. The periodic signal generator is configured to interpolate between the discrete points in the table of derivative values.
