It discusses the fundamentals behind the noise shaping operation and the two main implementation topologies. Error feedback and cascaded integrators feedforward topologies are … WebWithout any noise shaping, DDS Compiler reports an SFDR of 72 dB Using the same DDS configuration, I noticed that enabling the noise shaping features either have no effect (with phase dithering enabled, I still get a SFDR of 72 dB) or give worse SFDRs (66 dB for …
What is the gain (advantage) of oversampling and noise shaping …
Noise shaping is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit-depth reduction of a digital signal. Its purpose is to increase the apparent signal-to-noise ratio of the resultant signal. It does this by altering the spectral shape of the error that is introduced by dithering and quantization; such that the noise power is at a lower level in frequency bands at which noise is considered to be les… WebThe Intellivox-DSX280 HD is capable of providing a constant sound pressure level over a distance of up to 35 m, although a substantial extension of this range can be achieved in less demanding acoustical conditions. ...
