Abstract: PROBLEM TO BE SOLVED: To perform various kinds of measurements including a peak-to-peak width concerning ringing in the measurement of a waveform of an electric signal.
SOLUTION: The waveform measuring apparatus comprises a digital filter 10 which removes large amplitude change components from an input signal and outputs it while leaving small amplitude noise components as they are, a window generation section 20 which inputs the difference signal between the input signal and the output signal of the digital filter 10 and generates a window indicating the position of an edge part of the difference signal, and a ringing measuring section 30 which extracts a part indicated by the window generated by the window generation section 20 out of the output signal of the digital filter 10 and measures at least a peak-to-peak width of the extracted waveform.

Abstract: PROBLEM TO BE SOLVED: To attain signal processing capable of restoring an original signal by effectively removing impulsive noise to various signals including detailed signals and cyclic uneven signals, etc. SOLUTION: A signal restoration part 14 inputs signals to be processed to sequentially notice signal points and calculates restoration values at the noticed signal points by calculating an average value of signal values at signal points immediately before and immediately after the noticed signal points and correcting the average value using one or more difference values obtained from the plurality of signal points before or after the noticed signal points. In addition, a signal status determination part 13 checks the plurality of signal points before and after the noticed signal points and determines relation among the plurality of signal points including the noticed signal points. Then, the restoration values or input values by a signal restoration part 14 are selectively output regarding individual signal points according to statuses of the signals obtained from determination results.

Abstract: PROBLEM TO BE SOLVED: To inspect the actuation of a communication interface having simple structure and being used for a computer, etc. SOLUTION: When a wrap tool 40 is connected with an SCSI device 10, a signal (TEMPWR) from an output device 38 to recognize the wrap tool 40 is outputted to SCSI connectors 22, 24 by a Y-shaped cable 14, returned back at the wrap tool 40 and returned to an SCSI controller 12 as a signal (PSCSIWRAP) through registers 28, 30. Since one end of a register 26 the other end of which is grounded is connected with the input side of the SCSI controller 12, the registers 28, 30 are connected in parallel and the signal (PSCSIWRAP) is determined by the registers 26, 28, 30. When a single wrap tool is connected, a potential is determined by the registers, 26, 28 or 30 and eliminated.

Abstract: PROBLEM TO BE SOLVED: To stabilize a servo system in a tape drive system for performing the reading/writing operation of the tape by inserting a tape cartridge into a tape drive independently of the combination of the drive and the cartridge. SOLUTION: The coefficient of a low-pass filter for the servo control of the tape drive is reset in accordance with the inserted tape cartridge for every insertion of the tape cartridge into the tape drive. To put it concretely, a servo pattern being recorded on the tape of the tape cartridge inserted to the tape drive is read out, the frequency of this read out servo pattern is analyzed, a singular point exceeding the prescribed spectral range is detected from the frequency component obtained by this frequency analysis, and then the coefficient of the low-pass filter is set so as to negate the power spectrum of this singular point.

When the element 306 is not fixed to the carriage 202, the light from the LED 302 is made incident to the PSD 304 at a reference position A. When the carriage 202 and element 306 approach the inner and outer limits of the moving range of the carriage 202, the light is polarized to a second and third positions (B') across an increasingly long distance. The position of the carriage 202 is calculated by using basic trigonometry.
