Resulting optical noise factor is F pnf = SNR pnf,in / SNR pnf,out = 2n sp (1-1/G)+1/G. F pnf is in conceptual conflict [9] [10] with the electrical noise factor, which is now called F e: Photocurrent I is proportional to optical power P. P is proportional to squares of a field amplitude (electric or magnetic). So, the receiver is nonlinear in ...
An audio conversion app (also known as an audio converter) transcodes one audio file format into another; for example, from FLAC into MP3. It may allow selection of encoding parameters for each of the output file to optimize its quality and size.
The Y-factor method is a common measurement technique for this purpose. [1] By using a noise diode, the output noise of an amplifier is measured using two input noise levels, and by measuring the output noise factor (referred to as Y) the noise figure of the amplifier can be determined without having to measure the amplifier gain.

The judge in Sean "Diddy" Combs' sex-trafficking case has questions about the rap mogul's notepads. Someone wrote "Legal" on the pads in the days after prison officials took evidence photos of them.
Friis's formula is used to calculate the total noise factor of a cascade of stages, each with its own noise factor and power gain (assuming that the impedances are matched at each stage). The total noise factor can then be used to calculate the total noise figure. The total noise factor is given as
In “A City on Mars,” Kelly and Zach Weinersmith investigate what life would be like for humans on the red planet, arguing that Elon Musk’s dream is doomed to fail.
The hits keep coming for the Detroit Lions. Running back David Montgomery is out indefinitely after suffering a torn MCL, per multiple reports. The 27-year-old running back is reportedly ...
