Fixed point matlab code

WebWhen a fixed-point library function is not available, fixed-point applications require an approximation of the function. Often, an interpolated look up table is used to store an approximation of the function over a specified range. This example shows how to approximate the function y = sin (2*pi*x) over a specified input range using a lookup table. WebFixed-Point Arithmetic Addition and subtraction Whenever you add two fixed-point numbers, you may need a carry bit to correctly represent the result. For this reason, when adding two B-bit numbers (with the same scaling), the resulting value has an extra bit compared to the two operands used. a = fi (0.234375,0,4,6); c = a+a
