Analog and digital systems employed in the EXTREME1 for noise reduction include:
High-Speed Sigma-Delta Signal Conversion
High-Order Modulation Noise Shifting
Dual Digital Finite Impulse Response Filters
Analog Low-Pass Filter
These features allow for recordings to be made with high quality, high resolution, and low spurious noise. Oversampling, dual digital filters, and an analog low-pass filter insure that the recordings made will not contain NYQUIST FOLDING images.
