求英语高手人工翻译下，不胜感激！！！

本文介绍的是基于单片机的数字调频收音机设计。本设计，主要基于89c52单片机，TEA5767收音机芯片，数码管等元器件制作的。通过TEA5767收音机芯片完成87.50MHz到108.00MHz频率的广播信号接收和输出调频立体声音频信号，用TDA2822音频放大器可以调节耳机输出音量的大小。并且通过不同按键可以实现调频，电路复位等功能并在LED数码显示管上进行显示出来。和传统收音机相比，本设计的数字调频收音机具有体积小，调频精确度高，发音清晰，背景声音纯净，抗干扰能力强等优点。

Answer 1

This paper is based on SCM digital FM radio design. This design, mainly based on single-chip microcomputer, 89c52 TEA5767 radio chip, digital tubes made of components. Through the TEA5767 radio chips 87.50 MHz to the radio frequency MHz 108.00 signal receiving and output FM stereo audio signals, TDA2822 audio amplifier can be adjusted with the size of the headset output volume. And through the different keys can realize FM, circuit functions and reset in XianShiGuan on LED digital display. And traditional radio, this design than digital FM radio has small, FM high precision, the pronunciation, background sounds pure and strong anti-jamming capability, etc.

Answer 2

This article describes a microcontroller-based digital FM radio.
The design is mainly based on 89c52 microcontroller, TEA5767 radio chip, digital production and other components.
TEA5767 radio chip through the completion of 87.50MHz to 108.00MHz frequency FM radio signal reception and output stereo audio signals can be adjusted with a TDA2822 audio amplifier headphone output volume.
And frequency modulation can be achieved through different keys, reset the circuit functions and digital LED display on the display tube.
And traditional radio compared to the design of digital FM radio with small size, high accuracy frequency, articulate, background sound pure, anti-interference ability and so on.
