接收单元,我们采用的原理和调频收音机原理一样。图3为接收电路,以专用调频接收模块IC1 TDA7021T为核心,经解调后的音频信号从脚输出,送到IC2 LM386作功率放大,推动耳机发声。三极管BG9018等组成高频放大级,以提高接收灵敏度。调节可调电容器C23可以改变接收频率,使其对准发射机的发射频率。-Receiving unit, we have adopted the principle and the principle of like FM radio. Figure 3 for the receiver circuit to a dedicated IC1 TDA7021T FM receiver module as the core, after demodulation of the audio signal after the output from the feet, to make IC2 LM386 power amplifier, and promote sound headphones. BG9018 triode composed of high-frequency amplification level in order to improve receiver sensitivity. Conditioning adjustable capacitor C23 can change the receiver frequency so that it fired at the transmitter frequency.

winrar rarlng.dll 去广告语言文件
如果您不喜欢winrar弹出的广告,建议使用此软件。
如果您安装的winrar是从官方网站下载的 英文版,当打开软件的时候 会弹出广告,将此rarlng.dll放入安装目录下,程序的界面将变为中文,同时,不再弹出广告。如果您安装的是winrar汉化版,实际上是winrar的中国代理将原winrar.exe直接修改后的结果,不管是否注册,都会有广告。
