Nettet10. jul. 2009 · Abstract: The conventional double-modulated terahertz differential time-domain spectroscopy (double-modulated THz-DTDS) of liquids requires linear dithering of the sample to rapidly vary the sample thickness in order to produce the required sample and reference signals. Linear dithering, however, imposes a fundamental limitation as … In an analog system, the signal is continuous, but in a PCM digital system, the amplitude of the signal out of the digital system is limited to one of a set of fixed values or numbers. This process is called quantization. Each coded value is a discrete step... if a signal is quantized without using dither, there will be quantization distortion related to the original input signal... In order to prevent this, the signal is "dithered", a process that mathematically removes the harmonics or other high…

NettetIn the context of solving linear equations we have introduced the notion of a vector and a matrix. The result is a compact notation for representing linear equations, A~x =~b. … NettetDither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Unfortunately, this means you may have to use images. If you do decide to use a repeating image for a gradient, make sure you leave enough width or height for the dithering to work.
