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]
A few days ago, I bought an 8LED flashlight in the market (the flashlight uses No. 5 batteries). Because I had other things to do, I didn't pay attention when purchasing it. When I got home and use...[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]
Synchronous buck designs are becoming increasingly difficult, and the selection of suitable ICs is becoming quite narrow. This Design Idea combines a current-mode PWM IC used in a flyback regulator...[Details]
