i] refers the initial phases of sine waves, but not cosine waveforms, which are often used when discussing minimization algorithms of crest factor
(CF) as in .
The analyzer measures power, current, peak-to-peak voltage, and crest factor
either continuously or as a single operation.
It is ideally suited for the high crest factor
, high bandwidth, complex modulated 2G, 3G, and 4G signals that are output from RF DACs and integrated transceivers.
Although, the OFDM signal has many advantages, such as robustness against inter-symbol interference (ISI), experiences very high Peak to Average Power Ratio (PAPR) or Crest Factor
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.
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
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.
