8. 000 Hz When the sampler modulates frequencies out of the Nyquist bandwidth back to the 0 to 500 Hz baseband it is called aliasing Signals which are not pure sine wave can have many components harmonics above the Nyquist frequency These harmonics are erroneously aliased back to the baseband added to parts of the accurately sampled signal and produces a distorted data set To block frequencies out of the Nyquist bandwidth a lowpass filter is applied to the signal before it reaches the sampler Each input channel has its two pole anti alias lowpass filter with a cutoff frequency of about 250 kHz The very high cutoff frequency allows an extremely flat frequency response in the bandwidth of interest and a small phase error The analog filter precedes the analog sampler The analog sampler operates at 256 times the selected sample rate for rates below 51 2 kS s 128 times for rates between 51 2 kS s and 102 4 kS s For rates over 102 4 kS s the oversampling is 64 times That means the ADC operates at 13 1072 MS s if you select a sample rate of 102 4 kS s 128 102 4 kS s The 1 bit oversampled data is passed to a digital anti aliasing filter This filter has no phase error and an extremely flat frequency response It also has an extremely sharp roll off near the cutoff frequency 0 38 to 0 494 times the sample rate and the rejection above 0 5465 times the sample rate is greater than 92 dB The output stage of the digital filler resamples higher

11. 2 kHz Nyquist frequency It also re samples the data to the more conventional rate of 102 4 kS s A 1 bit quantizer introduces many quantization errors to the signal The 1 bit 13 1072 MS s from the ADC carry all information to produce 24 bit samples at 102 4 kS s The delta sigma ADC converts from high speed to high resolution by adding much random noise to the signal In this way the resulting quantization noise 15 restricted to frequencies above 100 kHz This noise is not correlated with the useful signal and is rejected by the digital filter ADCs can only represent signals of a limited bandwidth The maximum frequency you can represent is the half of the sampling rate This maximum frequency is also called Nyquist frequency The bandwidth between 0 Hz and the Nyquist frequency is called Nyquist bandwidth Signals exceeding this frequency range can not be converted correctly by the sampler Page 11 Printing version 2 1 AUG2010 DEWE 43 For example the sample rate is 1000 S s the Nyquist frequency is 500 Hz If the input signal is a 375 Hz sine wave the resulting samples represent a 375 Hz sine wave If 625 Hz sine wave is sampled the resulting samples represent 375 Hz sine wave too This happens because signals exceeds the Nyquist frequency 500 Hz The represented frequency of the sine wave is the absolute value of the difference between the input frequency and the closest integer multiple of the sampling rate in this case 1
