Abstract
A sampling scheme that is based on multiple level-crossings is present ed. This scheme generates samples of the input signal that are nonunif ormly spaced in time by recording the time instants at which the signa l crosses any of the fixed quantization levels. The nonuniform sample sequence is transformed to uniform samples by polynomial interpolation . The resolution is further increased by employing decimation. Various trade-offs involved in terms of speed, resolution and hardware comple xity are discussed.
