WebMay 6, 2024 · 首先，必须深刻理解quantier这个函数的应用，它的基本思想是将浮点数转化为定点，中间是二进制的过度过程。对于quantizer后面两个参数[a,b]，a代表整数的(二进制表示)字长，b代表小数(二进制表示)的幂长。转载下面的例子便于理解：浮点转换为定点的过程在Matlab中称为量化，使用quantizer和quantize两个 ... WebUse fixed.Quantizer to reduce the word length that results from adding two fixed-point numbers. q = fixed.Quantizer x1 = fi (0.1,1,16,15); x2 = fi (0.8,1,16,15); y = quantize (q,x1+x2)

WebCreate a quantizer object that describes a signed fixed-point data type having a word length of 4, and fraction length of 2, saturate on overflow, and round to floor. Find the numerical range of the quantizer object q and return the result in separate output variables. q = quantizer ( 'fixed' , [4 2], 'floor' ); [min_q, max_q] = range (q) WebQuantization replaces each real number with an approximation from a finite set of discrete values. Most commonly, these discrete values are represented as fixed-point words. Though any number of quantization levels is possible, common word-lengths are 8-bitquantization noise because of its stochastic behavior. The more levels a quantizer uses ... WebUse quantize to quantize data to a fixed-point type with a wordlength of 3 bits, a fraction length of 2 bits, convergent rounding, and wrap on overflow. q = quantizer ( 'fixed', 'convergent', 'wrap' , [3 2]); x = (-2:eps (q)/4:2)'; y = quantize (q,x); Warning: 33 overflow (s) occurred in the fi quantize operation. go to daily
