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...

In the latter case, the presence of a peak on the noise floor is due to some direct cross-talk between the RF synthesizer and the spectrum analyzer through the RF injection and detection circuits. The normalization to 1 allows the comparison at different frequencies. We can detect a signal ...
Amplitude modulation refers to a process where the frequency components of a modulating signal are shifted to occupy a different position in the spectrum by multiplying the time functions of the modulating signal and carrier together. It includes systems like Double-sideband suppressed carrier, Conventio...
- 《Review of Scientific Instruments》 被引量: 1发表: 2015年 Equipment for measuring amplitude and phase noise of signals in millimeter wave This equipment allows making measurement with high sensitivity at low input power. The sensitivity of amplitude noise spectrum measurement is minus 152 dB/Hz...
white noise, pink noise, and Brownian (red) noise, respectively41. The spectrum of EEG data is reported to be related to Brownian noise56,57, thus, the synthesized data was generated from Brownian noise. First, 10 seconds of Brownian noise data was generated at a sampling frequency of ...
An ANOVA shows that speech recognition is significantly influenced by type of hearing protector and by noise spectrum. The interaction between these factors was not statistically significant. In general, the test subjects obtained somewhat better speech recognition thresholds in noise when wearing ...
Multiple-access digital communications is considered with direct-sequence spread-spectrum (DS-SS) quadrature amplitude modulation and quaternary spreading in each transmission. Each transmitted signal undergoes attenuation and a delay at a receiver in the additive white Gaussian noise channel. The receiver...
