Using Integers and FIR Filters with Filter Design Toolbox

---

Using integers when filtering with FIR filters can make it easier to work with certain classes of hardware, such as FPGA and ASIC processors. In some cases, it is convenient to work directly with integers when designing your filter. This chapter explores a few of the issues that commonly arise when using integers with FIR filters.
