Compare th. signal-to-quantization-noise ratio for two signals, both modeled by laplacian statis tics, one with a standard deviation of 0.4 V, the other with a standard deviation of 0.02 V. WebThe measured signal-to-noise ratios (SNRs) are 14.3 dB using the regular sampling system and 21.0 dB using the oversampling system. Since = 4, the achieved signal is expected to have 4-bit quality ( bit improvement). From simulation, we achieve an SNR improvement of approximately 6dB.
