| + | ===Algorithm Description=== | ||
| + | A standard subtraction operation is performed. When the algorithm is grown new input pins appear. These input pins represent more subtrahend terms so that the resulting output formula is:\\ | ||
| + | Output_Pin 0 = Input_Pin 0 - (Input_Pin1 + Input_Pin2 + Input_Pin3 + ... Input_PinN) | ||
| + | |||
| + | |||
| + | ===Example=== | ||
| + | The subtraction block can be used along with other arithmetic operators to realize many typical DSP functions. It is a basic building block that allows difference operations to be performed. | ||
| + | |||
| + | The subtraction block can also be useful when debugging a schematic project. In the following example subtraction is used to compare the output of the [[resources: | ||
