Sampling rate conversion (SRC) is usually performed in the time domain by using the operations of up-sampling, filtering, and down-sampling. However, it is also possible to perform the SRC in the frequency domai
Sampling vs Frequency Response: The sampling frequency must be at least twice as high as the highest frequency that you wish to reproduce because you must have at least 1 data point for each half cycle of the audio waveform. The highest frequency that you can record with a sampling rate of...
Impairments: Sample rate offset (SRO): -100.0 PPM Residual carrier frequency offset is added to the waveform using the helperFrequencyOffset function. In this example we assume the same oscillator is used for sampling and modulation, therefore the CFO will be a function of the SRO and ca...
It can be attributed to the fact that the increase in step size decreases the symbol rate which in turn increases the overall phase rotation due to CFO. Figure 9 shows the Q-factor values achieved for the various step sizes and various frequency offsets for 100 kHz laser linewidth. From ...
These new low-frequency artifacts are calledaliases(because high frequencies are “masquerading” as low frequencies), and the resulting signal is said to be aliased. (a) When the sampling rate is too low, the copies of the function’s spectrum overlap, resulting in (b) aliasing when ...
that the temporal resolution of the final reconstructed signals through the model was the same as that of the original high-sampled signals before the downsampling in Fig.1a. The restored outputs were compared with high-frequency GT spikes measured at the high sampling rate to evaluate the ...
The 44.1 kHz sampling rate used for Compact Disc was chosen for this and other technical reasons [3]. D. Harris (Ed.): EPCE 2014, LNAI 8532, pp. 265–271, 2014. © Springer International Publishing Switzerland 2014 266 X. Qin Although having a sampling frequency more than twice the ...
Equivalent time sampling increases the effective sampling rate of an oscilloscope for repetitive signals.
Different windows support different applications, and choosing the right one is not an easy task. Given that the signal contains strong interfering frequency components distant from the frequency of interest, a window with a high roll-off rate (e.g., a Hanning window) for the side-lobes should...
The circuit is optimized to process a 65 MHz bandwidth IF signal centered at 140 MHz with a sampling rate of 184.32 MSPS. The SNR and SFDR measured with a 140 MHz analog input across the 65 MHz band are 70.1 dBFS and 80.9 dBc, respectively. ...
