Consider the example of lowering the noise figure of a direct broadcast satellite (DBS) receiver. One option for improving receiver noise figure is to increase the transmitter power, however, this option can be very costly to implement. A better alternative is to substantially improve the ...
and there are other signals disrupting your desired signal. Again, it would make the task of the receiver exponentially more challenging to decipher the desired signal. In summary, this is what makes having a high signal to noise ratio so important. Furthermore, in some cases, this...

Low noise amplifier, amplifier with low noise figure. It is generally used as high-frequency or intermediate frequency preamplifier of various radio receivers and amplification circuit of high-sensitivity electronic detection equipment. When amplifying a weak signal, the noise of the amplifier itself ma...

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...

Enthusiasm Is Everything “The key to the best blow jobs is not how deep you take it, but the level of enthusiasm you have,” says Engle. “Make some noise, get everything as wet as possible, and just really put your heart into it.” ...
The main limiting factor in any radio receiver is the internal noise that is generated. For many radio communications applications either the signal to noise ratio or the noise figure is used.However for dynamic range specifications a figure called the minimum discernible signal (MDS) is often ...
