Portable Sound Recording Kit
You are lab technicians for a natural sciences research institute and are required to put together a purchase request for a portable sound recording kit, with the following mandatory features:
1. Light enough for a single person to carry and operate (preferably < 10Kg ?15Kg).
2. 100% battery operated, with a minimum autonomy of 10h.
3. Should include:
a) a directional (supercardioid or shotgun) pro audio microphone: - frequency response at least 40Hz ?20kHz
- sensitivity > -34dB (20 mV/Pa)
b) a high quality pro audio microphone preamp: - THD* < 0.01%
- SNR > 110dB
c) a set of high quality, adjustable, analog filters for narrowing the range of the captured sound around certain
frequencies within the audio band.
d) a portable A/D converter: - resolution >= 24bit / sampling rate >= 96kHz
- output format: S/PDIF or AES
e) all the necessary accessories (cables, connectors, adapters, batteries, carry case, etc.).
Your department manager expects your presentation in 7 days, as follows:
a) Block diagram of the system
b) List of system features
a) Detailed bill of materials (BOM)
b) Original manufacturer's data-sheets for the microphone, pre-amplifier and ADC (.pdf, .doc, etc.)

翻译出来是这样的:
便携式录音盒
你是实验室的技术人员为自然科学研究所和需要放在一起的购买请求便携式录音盒,与下面的强制功能:
1。光足够一个人携带和操作(最好是< 10公斤?15公斤)。
2。100%电池操作,以最小的自治10。
3。应包括:
(一)方向指向性或猎枪)专业音频麦克风:频率响应至少40 Hz?电池
敏感性> - 34db(20毫伏/尼龙)
乙)高质量的专业音频麦克风前置放大器:-这* < 0.01%
- > 110db信噪比
三)一套高质量的模拟滤波器,可调,缩小范围的捕获声音的
频率在音频带。
四)便携式模数转换器:分辨率> = 24位/采样率> = 96khz
输出格式的过程或光谱
五)所有必要的配件(电缆,连接器,适配器,电池,携带盒,等。)。
你的部门经理,期待你的表现7天,如下:
一个)的系统框图
乙)系统列表功能
