Selection of optimal predictor coefficient for various quantizers implemented in a delta modulation scheme with fixed predictor
It is seen in recent literature that such linear VCQO is a useful functional block which finds wide range of applications in emerging fields; namely, in certain telemetry-related areas it could convert a transducer voltage to a proportional frequency which is then modulated for subsequent processing [22], as quantizer for frequency-to-digital or time-to-digital conversion [23] and also as the spectrum monitor receiver [24] in cognitive radio communication studies.
Pi being the code-point closest to x, and p(x) denotes the pdf of x, can be obtained more efficiently by means of higher dimensional quantizers (see [8]).
Striving for higher precisions in measurement technology naturally leads to methods, which can shift the resolution limit of the quantizer usually represented by the analog-to-digital converter (ADC) under the lowest significant bit (LSB).

SPIHT and other type of zero tree quantizers, such as SLCCA [16] and MRWD [17], achieve good performance by exploiting the spatial dependency of the pixels, which are in different subbands after scalar wavelet transform.
Subjective perception of quantization error greatly varies with the frequency and it is advantageous to use coarser quantizers for the higher frequencies.
As an example, fully functional 4-bit quantizers operated at a sampling speed of 2 GS/s and exhibited 8-bit static accuracy.
One is multiple description coding with randomly offset quantizers (MDROQ), the other is multiple description coding with uniformly offset quantizers (MDUOQ), where the closed-form expression of theoretical performances is obtained for any value of M.
