Cross-Correlation by Single-bit Signal Processing for Ultrasonic Distance Measurement
Ultrasonic distance measurement using the pulse-echo method is based on the determination of the time of flight of ultrasonic waves. The pulse-compression technique, in which the cross-correlation function of a detected ultrasonic wave and a transmitted ultrasonic wave is obtained, is the conventional method used for improving the resolution of distance measurement. However, the calculation of ...

برای پردازش سیگنال آنالوگ در شبکه های عصبی ، معمولا نیاز به یک واحد حافظه آنالوگ احساس میشود که بدون احتیاج به a/d وd/a بتواند بطور قابل انعطاف و مطمئن اطلاعات آنالوگ را در خود ذخیره کند. این واحد حافظه باید دارای دقت کافی ، سرعت بالا ، توان تلفاتی کم و سایز کوچک باشد و همچنین اطلاعات را برای زمان کافی در خود نگهدارد. برای پیاده سازی سیستمی که همه این قابلیتها را در خود داشته باشد، کوشش...
15 صفحه اولA high accuracy ultrasonic distance measurement system using binary frequency shift-keyed signal and phase detection
A highly accurate binary frequency shift-keyed ~BFSK! ultrasonic distance measurement system ~UDMS! for use in isothermal air is described. This article presents an efficient algorithm which combines both the time-of-flight ~TOF! method and the phase-shift method. The proposed method can obtain larger range measurement than the phase-shift method and also get higher accuracy compared with the T...
متن کاملThe Correlation of Brody High Resolution Computed Tomography Scoring System with Clinical Status and Pulmonary Function Test in Patients with Cystic Fibrosis
Background: To reduce the mortality and morbidity rates of cystic fibrosis (CF) patients, and to have an effective clinical management, it is important to monitor the progression of the disease. The aim of this study was to evaluate the progression of lung disease in CF patients by means of assessing the correlation of the CT scoring system with clinical status and pulmonary function test at th...
متن کاملPulsed photoacoustic Doppler flowmetry using time-domain cross-correlation: accuracy, resolution and scalability.
The feasibility of making spatially resolved measurements of blood velocity using a pulsed photoacoustic Doppler technique in acoustic resolution mode has been investigated. Doppler time shifts were quantified via cross-correlation of photoacoustic waveform pairs generated within a blood-simulating phantom using pairs of light pulses. The phantom comprised micron-scale absorbers imprinted on an...
