preamplifier

前置放大器

Preamplifier

前置放大器是一个电子放大器,它准备一个小的电信号进行进一步的放大或处理。 前置放大器通常靠近传感器放置,以减少噪声和干扰的影响。 它用于提高信号强度,以将电缆驱动到主仪器,而不会显着降低信噪比。 前置放大器的噪声性能至关重要; 根据Friis的公式,当前置放大器的增益高时,最终信号的SNR由前置放大器的输入信号的SNR和噪声系数决定。 在家用音频系统中,术语“前置放大器”有时可用于描述仅在不同线路电平源之间切换并应用音量控制的设备,使得不会涉及实际的放大。 在音频系统中,第二放大器通常是功率放大器。 前置放大器提供电压增益但没有显着的电流增益。 功率放大器提供驱动扬声器所需的较高电流。 A preamplifier is an electronic amplifier that prepares a small electrical signal for further amplification or processing. A preamplifier is often placed close to the sensor to reduce the effects of noise and interference. It is used to boost the signal strength to drive the cable to the main instrument without significantly degrading the signal-to-noise ratio. The noise performance of a preamplifier is critical; according to Friis's formula, when the gain of the preamplifier is high, the SNR of the final signal is determined by the SNR of the input signal and the noise figure of the preamplifier. In a home audio system, the term 'preamplifier' may sometimes be used to describe equipment which merely switches between different line level sources and applies a volume control, so that no actual amplification may be involved. In an audio system, the second amplifier is typically a power amplifier. The preamplifier provides voltage gain but no significant current gain. The power amplifier provides the higher current necessary to drive loudspeakers.

在英语 词典里preamplifier的定义

字典中的前置放大器的定义是用于改善电子设备的信噪比的电子放大器。 在传送到主放大器之前,它将一个低电平信号提升到一个中间电平。有时缩短到:前置放大器。

The definition of preamplifier in the dictionary is an electronic amplifier used to improve the signal-to-noise ratio of an electronic device. It boosts a low-level signal to an intermediate level before it is transmitted to the main amplifier Sometimes shortened to: preamp.
