The TI LMX2594 wideband PLLatinum RF synthesizer, available from Mouser Electronics, is a high-performance wideband phased-locked loop (PLL) RF synthesizer with an integrated voltage-controlled oscillator (VCO) that can generate any frequency from 10 MHz to 15 GHz without using an internal frequency doubler, eliminating the need for complex onboard filters to remove subharmonics
The requirements for current harmonics, subharmonics
, and interharmonics specify the allowable distortion as a function of multiples of the fundamental frequency of the input voltage.
Additional requirement is that the stimulating frequencies cannot be harmonics or subharmonics
from each other .
From the frequency spectrums of all the UPSs it is clear that outputs of all the uninterruptible power supplies contains subharmonics
, harmonics and Interharmonics.
Control of frequency spectrum in terms of variable sound quality, including register, twang, belt, breathiness, subharmonics
, roughness, gender equalization, and primal vocalization for emotion--all produced with an eye toward vocal endurance and longevity.

Typical spurious for the two models is at -80 dBc, with typical harmonics of-40 dBc and subharmonics
at -25 dBc.
Their results confirm the previous trend quoted above on subharmonics
enhancement in elastic liquids.
2] gives two subharmonics
with an amplitude proportional to the square of the over constituents [M.
The balance and output match characteristics of these multipliers ensure a typical 20 dB suppression of all subharmonics
The Model 6139-6458 features 100 [micro]sec switching speed and low harmonics (-15 dBc); subharmonics
(-35dBc) and spurious (-60 dBc).
The VSA-1215 allows the user to go down to 1 Hz and even below that, if he needs to, so he can actually see what's happening at low frequencies Co especially subharmonics
on machines with operating speeds from 1,800 RPM to below 600 RPM.
