1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
