A gyroscopic sensor includes a vibratory gyroscopic sensor element, first and second drive electrodes positioned proximate to the vibratory gyroscopic sensor element, and a drive circuit operatively connected to the first and second drive electrodes. The drive circuit is configured to generate a stepped sinusoidal waveform having a plurality of steps, each step having a predetermined duration and each step having an output level in a plurality of predetermined output levels for the stepped sinusoidal waveform including at least three positive output levels and at least three negative output levels to generate oscillation of the vibratory gyroscopic sensor element at a predetermined frequency. |
