interaction law of single-phase VSC.
where [phi] is the lagging angle of phase current compared with back-EMF and [I.sub.1], [1.sub.5], [1.sub.7], and [I.sub.11] are the amplitudes of fundamental harmonic
and the 5th, 7th, and 11th current harmonics
At the heart of the headend is Harmonic
's video encoding platform, which increases SD/HD MPEG-4 AVC encoding efficiency and enables TBC to deliver superior video quality to subscribers by utilizing advanced motion estimation, refined multi-pass encoding and preprocessing capabilities.
However there are loads and devices on the system that have nonlinear characteristic which is affected both voltage and current signal and result in harmonic
distortion causing poor power quality.
These methods only work properly if the signal is composed of only the fundamental and harmonic
frequencies in a certain frequency range.
The conventional circuit of the transistor and the corresponding harmonic
control network is shown in Figure 2(a) .
This paper proposes a new and simple method to find Harmonic
Sequences, just with one operation for each sequence, which makes the calculation much easier and faster.
"At IBC2019, we're drawing from our extensive deployment experience and showcasing concrete solutions deployed in the field by leading service providers, broadcasters and content owners," said Tim Warren, senior vice president and chief technology officer at Harmonic
. "The video market is highly dynamic, and consumer demand for live OTT services is growing.
Thierry Fautier, vice president of video strategy at Harmonic
, will outline the opportunities that 5G networks promise and the challenges ahead for 8K in his Taking a Look at 8K and 5G Technologies presentation on Sept.14 at 1:50 p.m.
Based on management's projections, Harmonic
analysts modeled for a loss of 7 cents per share on sales of $85.07 million.
Featuring a software-based, cloud-deployable application supporting features such as HDR, Harmonic
's UHD solution enables the operator to deliver exceptional video quality while maximizing bandwidth efficiency.
However, this technique doesn't allow controlling of the desired harmonic
order, total harmonic
distortion (THD) and modulation index.
