Abstract: Butterfly calculations of a cardinal number of four and butterfly calculations of a cardinal number of two are performed by using the same circuitry. When butterfly calculations of a cardinal number of two are performed, predetermined lines in the circuitry are removed by using selectors. Moreover, the multiplication factors of the signal lines which join predetermined complex multiplication circuits with predetermined complex addition circuits are changed from -j to -1, from -1 to 1, from -1 to 1, and from -j to -1. As a result, a pair of butterfly calculating circuit systems (A and B) are formed. On the other hand, when calculations of a cardinal number of four are performed, all the signal lines in the circuitry are connected, and the predetermined multiplication factors of the respective paths are set. As a consequence, a single butterfly calculating circuit system having a cardinal number of four is formed.

Abstract: A television receiver having a signal input terminal supplied with an interlace video signal and a signal coverter connected to the input terminal for converting the interlace video signal to a non-interlace signal to be displayed. The signal converter includes a signal inserting circuit for inserting new line signals between two successive line signals of the interlace signal, the new line signals being formed by interpolating one of the preceding and succeeding line signals in the interlace signal. A three dimensional filter is connected to the signal converter for attentuating vertical and horizontal high frequency components in the non-interlace video signal only when the non-interlace signal includes both of the vertical and horizontal high frequency components.
