The general signal-flow graph
for the proposed fast DCT algorithm given, while the signal-flow graphs
of 2-point DCT, 4-point DCT, and 8-point DCT are respectively represented where the angles in the circles are used to represent CORDICs with this rotation angles.

approach," Microelectronics Journal, vol.
Over the course of six chapters he provides an introduction to the photonic components essential for photonic processing systems, discusses the representation of photonic circuits using signal-flow graph
techniques, describes photonic signal processors such as differentiators and integrators, examines applications in the generation of solitons and in optically amplified fiber transmission systems, illustrates the compensation of dispersion using photonic processors, and explains the design of optical filters using photonic processing techniques.
The filter was firstly designed in its S-E form using signal-flow graphs
(SFGs) method and subsequently transferred into its F-D form by mirroring passive/active elements.
