His topics include linear systems and identification, modeling power amplified nonlinearities, memory effects, reducing the crest factor
of digital communication signals, and frequency domain models.
The 61800 series is also able to provide precision measurements such as RMS voltage, RMS current, true power, power factor, current crest factor
and many others.
The first is based on scalar measurements such as root mean square (RMS), crest factor
and the kurtosis  which gives a reasonably global defect indication without the possibility of its location in the bearing.
(ii) Crest Factor
(C) or Peak-to-Average Ratio (PAR), that is, the peak amplitude of the waveform divided by the rms value of the waveform s(t):
Unlimited crest factor
and 100% load step capability
"Customers are able to rapidly evaluate Xilinx's crest factor
reduction (CFR) and DPD algorithms in conjunction with ADI's high-performance transmitter solutions, saving considerable engineering time.
Customers can further speed time-to-market with a complete signal chain for software defined radio and test equipment: dual, 16-bit, 1-GSPS digital-to-analog converter (DAC) (DAC5682Z); wideband, fully differential amplifier (THS4509); programmable digital up and down converter (GC5016); digital pre-distortion solution with crest factor
reduction (GC5325); direct quadrature modulator (TRF3703); frequency synthesizer (TRF3761); low-jitter clock generator and synchronizer (CDCE62005, CDCE72010); and high-performance digital signal processors (DSP) (TMS320C6472).
* Vibration level--rms, exponential, peak, crest factor
A factor, sometimes called crest factor
, is multiplied by the background noise voltage to determine the threshold.
In addition to the versatile DAC5687, TI also offers additional low power analog parts and high performance DSPs, including the new GC1115 wideband crest factor
reduction processor and TMS320TCI6482 DSP.
They have focused on the voltage drift caused by temperature changes or the voltage variation according to the crest factor
in a modulated system.
A filter/vibrometer option is designed to turn the unit into a hand-held digital vibration meter that can measure acceleration (rms, peak, and crest factor
), filtered rms velocity and filtered peak to peak displacement allowing measurements when collecting spc data on a predictive maintenance route.
