Abstract :
A general approach is presented for implementing discrete transforms as a set of first-order or second-order recursive digital filters. Clenshaw´s recurrence formulae are used to formulate the second-order filters. The resulting structure is suitable for efficient implementation of discrete transforms in VLSI or FPGA circuits. The general approach is applied to the discrete Legendre transform as an illustration
