Designing Raised Cosine Filters

The rcosine function designs (but does not apply) filters of these types:

• Finite impulse response (FIR) raised cosine filter

• Infinite impulse response (IIR) raised cosine filter

• FIR square-root raised cosine filter

• IIR square-root raised cosine filter

The function returns the transfer function as output. To learn about applying raised cosine filters, see Filtering with Raised Cosine Filters.
