有源滤波器的快速实用设计_电子书

说明：  矢量网络分析仪的基本原理，内容详细，实用！(Basic Principle of Vector Network Analyser)

说明：  基于51/52单片机 1，探测环境温度，以LCD1602 做显示单元 2，可设置上限/下限数值，从而做到警报的提醒及应急设施的启动 3，超过设置限值时，会启动 LED 、蜂鸣器以及电机（仿真时使用）应用可使用其他代替(Based on 51 / 52 single chip microcomputer 1. Detect the ambient temperature with LCD1602 as the display unit 2. The upper / lower limit value can be set to remind the alarm and start the emergency facilities 3. When the setting limit is exceeded, the LED, buzzer and motor (used in simulation) application will be started, and other alternatives can be used)

说明：  Basic principle of LDPC code and FPGA implementation of LDPC code

基于51单片机的简易电子时钟，能实现校时。(Electronic clock, can achieve timing.)

制作电子负载，恒压、恒流、恒阻的情况。有原理图、PCB板，可以参考一下。(Make electronic load, constant pressure, constant current, constant resistance. There is a schematic diagram, PCB board, can be referred to.)

对delta sigma进行设计，实现delta sigma ADC的设计(this is use for delta sigma adc ,and design and achieve adc)

说明：  微带滤波器设计，包括低通、带通和高通三型滤波器参数设计，能够设置频率范围，自动生成滤波器参数。(Microstrip filter design, including low-pass, band-pass and high pass filter parameter design, can set the frequency range, automatically generate filter parameters.)

FloTHERM的使用入门手册，写的很好(FloTHERM Introduction Manual, well written)

单片机电容触摸屏硬件PCB设计，layout(Microcontroller, capacitor, touch screen, hardware, PCB design, layout)

超声波模块制作了一个测距装置，HC-SR04自身不带温度补偿功能，所以加上一个使用DS18B20做的温度测量模块。整个系统包括：51单片机最小系统，超声波测距模块、温度测量模块、液晶显示模块。(The ultrasonic module has made a distance measuring device, HC-SR04 does not have temperature compensation function, so add a temperature measuring module using DS18B20. The whole system includes 51 single chip microcomputer minimum system, ultrasonic ranging module, temperature measurement module and LCD module.)
