Oversampling ratio formula

Oversampling Description Increasing the oversampling ratio (OSR) results in overall reduced noise and the DR improvement due to oversampling is ΔDR = 10log10 (OSR) in dB.

What is the oversampling ratio?

Oversampling Rate – this is a resampling rate based on the original sampling rate. For example, if the original sample rate is 48 kHz, an oversampling rate of 2x infers a resampling or upsampling rate of 96 kHz. Upsampling – the process of resampling a signal at a higher rate than the incoming signal.

What is oversample factor?

Oversampling factor specifies the factor by which the global clock signal is a multiple of the base rate at which the model operates. Use the Oversampling factor to integrate the DUT with a larger system that supplies timing signals to other components in the system at the global oversampling clock.

What is 8x oversampling?

The audio industry has now standardized at an 8x oversampling rate, which means a CD's sampling frequency is increased to 352.8kHz before it enters the digital-to-audio converter. This effectively moves the aliasing frequencies to values near 300kHz, much higher than the original 22.05kHz.

What is oversampling effect?

In signal processing, oversampling is the process of sampling a signal at a sampling frequency significantly higher than the Nyquist rate. Theoretically, a bandwidth-limited signal can be perfectly reconstructed if sampled at the Nyquist rate or above it.
