| Abstract: | The linear phase place with strictness and the wanton range characteristic of FIR wave filter can meet the digital TV requisition for real-time processing and hi fi (high fidelity) of the signal. Computer programs can already be utilized at present to make the design of FIR wave filter simplify greatly. Therefore, the linear phase place FIR wave filter is widely used in the brightness and the color of signal while separating the circuit in Digital TV. |
