Title: Parameter input method for verification of logical design
Inventor: BURUUSU WAIRU
IPC: G06F17/50
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a system (namely, a tool set) for verifying logic on a logic design level. SOLUTION: A stimulus from the outside for logic design is derived from a series of timing drawings generated in accordance with the interface protocol of logic design being a verification object. A timing drawing editor 18 supplies a graphical user interface 16 by which a logic designer can describe his own logic by using a general-purpose timing drawing into which the permutation of interface specification is incorporated. The output of the timing drawing editor 18 is a file for describing the interface of the logic and the plural timing drawings where the different and various interface interactions are mentioned can be stored in the file. A suitable simulation driver reads the file generated by the timing drawing editor 18, and obtains the interface mentioned in the file. Then, simulation/randomization algorithm are applied for operating the interface in an appropriate situation for the interface mentioned in the timing drawing.

Title: Uhf tuner
Inventor: SUZUKI MASAKAZU
IPC: H03J3/06
Filed: 1989-07-19
Abstract: PURPOSE:To reduce a gain difference between a high frequency channel and a low frequency channel by providing a series resonance circuit comprising a coil and a capacitor between an input of a mixer circuit comprising a double balanced mixer and ground and selecting the constant of the coil and the capacitor. CONSTITUTION:A series resonance circuit 8 comprising a capacitor Co and a coil Lo is added between an input of a mixer circuit 5 comprising a double balanced mixer of a UHF tuner and ground. A gain of a high frequency channel of an RF signal passing through an interstage tuning circuit 3 is higher than a gain of a low frequency channel by a 2nd RF amplifier circuit 4 comprising a common base transistor(TR) and the mixer circuit 5 comprising a double balanced mixer. However, the constant of the capacitor Co and the coil Lo of the series resonance circuit 8 is selected to deteriorate the transfer characteristic of high frequency without varying the transfer characteristic of the low frequency, thereby correcting the gain difference of the entire tuner. Thus, the gain difference between the UHF high frequency channel and the UHF low frequency channel is decreased.
