Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]

1 Introduction Intelligent control instruments are one of the most commonly used controllers in industrial control. They are mainly aimed at a specific parameter (such as pressure, tempera...[Details]

With the advocacy and implementation of the government's Safe City Plan, the security market has increasingly higher requirements for the clarity of surveillance images. Imagine that after a case o...[Details]

This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]

With the widespread application of new services and technologies in the communications industry, the scale and capacity of operators' network construction are getting larger and larger, and the ris...[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]

introduction At present, the research on micron and nanotechnology is very active, which has led to the rapid development of microtechnology and micro-mechanical electronic system (MEMS) t...[Details]

The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]

The overall operating performance of an electric car depends first on its battery system and motor drive system. The drive system of an electric car is generally composed of three main parts: a con...[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]

1 Introduction The stepper motor is an actuator of an open-loop servo motion system, which is controlled in a pulse mode and outputs angular displacement. Compared with AC servo motors and DC servo ...[Details]

0 Introduction In microwave, radar, radio and television, and communication systems, the problem of coupling RF power is often encountered. A directional coupler is a directional power divide...[Details]
