An example of zero-mean white Gaussian noise with a variance of σn2 = 0.25 is shown in Figure 3.3(b). Even if this assumption may not hold in certain cases, it does help make the mathematical analysis of digital communication systems tractable. The receiver has to make a decision on ...
a digital-analog converter and filter and outputs an analog white noise frequency spectrum, and the inverse of the frequency spectrum is a compensation function of the white noise in a frequency domain; step 3, the compensation function of the frequency domain is converted to a time domain; and...
He points to an icon on the screen and continues to talk at me, but it’s likewhite noise. Assenyala una icona a la pantalla i continua parlant-me, però per a mi és comsoroll blanc. Literature In communication channel testing and modelling, Gaussian noise is used as additivewhite nois...
Interface, analog, and memory IP in the latest technology nodes can provide pre-verified building blocks that you can integrate into your design, saving time and effort in your design cycle. The IP also can help you meet your power and performance targets, solve integration and verification ...
Whatever’s happening on movie night, Active Voice Amplifier helps ensure you rarely miss a word. It analyses noise levels in your room and amplifies the dialogue, so that even if the dog’s barking or the kids are arguing, you can hear every word.* ...
A higher SNR allows you to precisely pinpoint the origin of enemy footsteps, or hone in on the location of gunfire or explosions on battlefield. With its quad-DAC design, ROG Delta White Edition is capable of achieving an unprecedented signal-to-noise ratio of 127 dB, a level untouchable ...
the monitor broadcasts masking noise through its own, or through a remote, speaker, thereby enabling the patient to rest more comfortably in a noisy institutional environment. If the patient does not move on his or her own accord within a predetermined turn interval, the masking sound broadcast...
This eliminates the audible noise which often occurs when the LED current is pulsed in replica of the frequency and duty cycle of PWM control. Unlike other scheme which filters the PWM signal for analog dimming, TPS61160, TPS61161 regulation voltage is independent of the PWM logic voltage level...
