Room 7: Interleaved Continuous Conduction Mode Power Factor Correction Boost Converter with Improved Modulated Carrier
Control Method, by H.
ADI s 14-bit dual-channel AD9117, 16-bit dual-channel AD9122 and 14-bit single-channel AD9739 transmit DACs were designed for signal synthesis applications, including pulse-modulated waveform generation and for synthesizing the modulated carrier
in quadrature digital architectures.
The end user's main aim was to have its own teleport for transmitting its five-channel bouquet -- DVB-S2 modulated carrier
-- on Arabsat and Nilesat satellites.
This modulated carrier
then feeds the antenna that radiates the data.
01 x Fundamental Test Level 10 Vrms (96 dB[mu]A in 150-[OMEGA] environment) Modulation 80% AM and pulse modulated carrier
using bulk-current injection
These simple pulses can be detected at increased distances by a factor of over ten relative to a modulated carrier
The resulting data set is large in comparison to linear network parameters, particularly when the input is similar to a digitally modulated carrier
Sensing technologies rely upon the conversion of a carrier signal into a modulated carrier
for which the modulation carries the information defining the measurand of interest.
Baseband signals, I and Q components, can be applied to modulators to create the required modulated carrier
Unlike conventional wireless systems, which use narrowband modulated carrier
waves to transmit information, Ultra-Wideband transmits over a wide swath of radio spectrum, using a series of very narrow and low-power pulses.
Bessel functions are used to calculate each FM spectrum component amplitude as a ratio of its peak sine wave voltage to that of the modulated carrier
, all as a function of M.
Performance information available from transponders include upstream/downstream RF frequencies and power levels, modulation, bandwidth, upstream packet loss rate, pre/post FEC error rates, and downstream signal-to-noise and modulation error ratios (SNR/MER) that are used to gauge the health of a digitally modulated carrier
