The 12 dB SINAD is a way of measuring sensitivity of radio receivers, but can also be applied to any analogue signal including binary signals as this article will explain.

The signal-to-noise and distortion ratio (SINAD) is a measure of the quality of a signal from a communications device, often defined as

apply a consistent standard definition of sensitivity. For voice modes we chose 12 dB SINAD for FM and 10 dB (S N)/N for AM, straight out of the ARRL product reviews. For SSB we adopted 10 dB above the minimum detectable signal (MDS) measured in the SSB bandwidth, adjuste

2020年1月23日 · SINAD値20dB（歪率-20dB）となるよう調整する。 SG出力レベルを変更するとSレベルが変化するので受信機ボリュームを定格出力に再調整する。 となり3μVEMF以下 …

信纳比 (SINAD，或S/（N + D））是均方根信号幅值与所有其他谱分量的平方和根的平均值的比值，包括谐波，但不包括直流。 SINAD很好地反映了ADC的整体动态性能，因为它包括了所有构成噪声和失真的部分。 5. 信噪比 SNR. 信噪比计算公式如下，与SINAD区别是计算时排除谐波分量。 6. effective-number-of-bits （ENOB） ENOB的计算公式如下。 输入满幅度情况： 输入非满幅度： 若读完本文有所获，请 “慷慨” 地点个赞，并分享公众号给周围朋友。 公众号专注蓝牙、WiFi …

Abstract: In this paper, SINAD performances have been experimentally revealed for RZ SSB, ACSB and narrow-band PM. It is found that RZ SSB is not affected as much as the others by fading. The RZ SSB spectrum efficiency is 1.5 ∼ 2.0 times larger than that of …

In this paper, the upper-bound for RZ SSB, determined from the thermal noise, has been experimentally revealed in SINAD performance. It is found that both an improved linearizer and a selective amplifier are useful in reaching the upper-bound and that the introduction of an amplitude limiter and a frequency discriminator for an RZ SSB signal ...

その中で、おもにFMの受信感度測定で使用される12dB SINAD法 受信機の出力 (簡単に言うとスピーカからの音)からすべての音 (相手の音声等)とノイズ＋歪 (目的の音以外)の比が12dB (約4倍差)になった時の高周波入力 (アンテナ端子)の値を受信感度とする

A typical specification might be that a receiver has a sensitivity of 0.25 uV [microvolts] for a 12 dB SINAD. Obviously the lower the input voltage needed to achieve the given level of SINAD, the better the receiver performance.

SINAD 是一个衡量模拟信号品质的指标，它是 Signal-to-Noise and Distortion Ratio 的缩写，中文常称为“信号到噪声及失真比”。 它综合考虑了噪声和失真对信号质量的影响，并将其与所需信号的幅度进行比较。
