ABSTRACT:
A digital signal to pulse converter including a spectral spreader which provides an adjusted clock signal that does not cycle during selected cycles. The adjusted clock signal is written into a multi-port content addressable memory which, as a function of the current count, provides output signals that determine a beginning or an end of a pulse within a frame. The spectral spreader varies the number of selected cycles to adjust the frame rate as desired, linearly or nonlinearly.
