In the flowcharts, hexadecimal values end with “h”, decimal values with “d”
Frequency variables used in computations are expressed in kHz, for example 1 GHz
is written as 1000000.
a. General description to find a value in a table
b. Example to find the value RFC_K corresponding to f
xx is a list of values stored in the first column of the map XY_map.
yy is a list of values stored in column in XY_map.
yy_out is the particular value of yy to find row n. xx(n
