Title: Method for measuring delay time of audio amplifier
Inventor: KASAHARA TOSHIHARU
IPC: G01R27/28
Filed: 1990-06-04
Abstract: PURPOSE:To shorten a measuring time by subjecting the response output from an audio amplifier due to the input of an impulse wave to discrete Fourier transformation and calculating a phase with respect to respective required frequency components from a complex spectrum to calculate the delay time difference between other respective frequency components to a reference frequency component. CONSTITUTION:An analogue impulse wave is inputted to an audio amplifier 12 to be measured from a signal generator 14. The impulse response output of the audio amplifier 12 to be measured at this time is converted to a digital signal by an A/D converter to be subjected to Fourier transform by a discrete Fourier transformation device 16 like an FFT. The impulse wave is a multiple sine wave having infinite frequency components respectively starting from a zero phase and the complex spectra of respective frequency components are obtained from the transformation device 16. From the real and imaginary parts of the complex spectra with respect to required frequencies among them, for example, 1 kHz, the phases of said frequencies (spectra) are operated and the delay time of these phases is operated. For example, 1 kHz is set to reference frequency and the delay time differences with other frequency components to the reference frequency are respectively calculated. By this method, the delay time of each required frequency can be obtained by one measurement and a measuring time can be markedly shortened. Further, a delay time can be measured even in such a case that the audio amplifier to be measured is digital input and output.

Title: Vehicle speed measuring apparatus
Inventor: ABETA TAKEHIRO
IPC: G01P3/488
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle speed measuring apparatus in which vehicle speed is measured using an electromagnetic pickup type rotation sensor and stoppage of the vehicle can be judged accurately based on the measurement. SOLUTION: A vehicle speed tSPD is operated (210-240) by counting vehicle speed signals SP1 generated from detection signals of a wheel speed sensor over a vehicle speed operation period. Judgement is made on whether the operated vehicle speed tSPD exceeds a stop judgement speed (310) and the tSPD is set as an engine control vehicle speed SPD (330) when it exceeds the stop judgement speed. When the tSPD is lower than the stop judgement speed, a decision is made (340, 350) whether that state sustains longer than a predetermined time required for single revolution of the wheel. When the state continues longer than the predetermined time, such a judgement is made that the vehicle is stopped and the control vehicle speed SPD is set at zero (370) otherwise, it is set at the stop judgement speed (360). According to the arrangement, stoppage of the vehicle can be judged accurately even if the detection signal level is lowered when the vehicle is travelling at an extremely low speed.
