Sensitivity, bit error ratio (BER) and noise figure are system parameters that characterize the ability to process low-level signals. Of these parameters, noise figure is unique in that it is suitable not only for characterizing the entire system but also the system components such as the pre-...
What Does Noise Figure Mean? Noise figure is a metric used to indicate the quality of amplifiers. It is the decibel representation of the noise factor that determines the sensitivity of the amplifier is decreased to an incoming signal due to its internal noise. It is defined as the ratio of...
When noise from the noise source passes through the DUT, the noise figure is calculated by measuring the SNR value at the DUT input (in the absence of the DUT) and the SNR at the DUT output (with the DUT). The noise figure (NF), measured in dB, can then be calculated with th...

Figure 1 As shown in Figure 1 the noise floor is better than -120 dB. Figure 2 shows that only signals above the noise floor can be measured with any degree of certainty. In this case, the signal level of -100dB at 20KHz could be measured. If, however, the noise floor increased abo...
Perhaps there is something to this idea, but even so, male primates are not known for needing a great deal of assistance in activating their ejaculatory reflex. If anything, the human male ejaculatory reflex tends to be too easily activated—at least from the perspective of women not being ...
The figure this year is predicted to be around 3.4 million, equal to around 7 percent of the adult population.Over a third of people said that the main turn-off about shopping on the high street is 0ver-crow-ding. Meanwhile almost a quarter said that long queues at the cheek-out are ...
In a typical phishing scam, ahackerpretends to be someone the victim trusts, like a colleague, boss, authority figure or representative of a well-known brand. The hacker sends a message directing the victim to pay an invoice, open an attachment, click a link or take some other action. ...
it won't be able to get through unless you chop the top off. From this, you can see that the signal‑to‑noise ratio will be different depending on how big the signal is, so when you see a written spec, you'll notice that the signal‑to‑noise figure is related to a specif...
