This block outputs a contiguous selection of bits from the input integer number.The Bits to extract defines the method by which the user select the output bits.
1- When "Upper Half" is selected the block outputs the half of the input that contain the most significant bit. In this case the third parameter "number of bits or index of bit" is ignored.
2- When "Lower Half" is selected the block outputs the half of the input that contain the least significant bit. In this case the third parameter "number of bits or index of bit" is ignored.
3- When "Range starting with most significant bit" is selected the block outputs certain number of bits of the input that contain the most significant bit. In this case the third parameter "number of bits or index of bit" defines the number of bits to extract.
4- When "Range ending with least significant bit" is selected the block outputs certain number of bits of the input that contain the least significant bit. In this case the third parameter "number of bits or index of bit" defines the number of bits to extract.
5- When "Range of bits" is selected the block outputs a range of bits of the input. In this case the third parameter "number of bits or index of bit" defines the range of bits to extract, it must be a vector with the format [start,end].
The extracted value depends on the forth parameter "Treat bit field as an integer". When it is set to 0 the input scaling is used to determine the output scaling. When it is set to 1, only the extracted bits forms the output number.
