About the above video:
Our most popular products are wireless video transmitters and receivers. autem, some clients require modification of the transmission frequency to meet local legal demand, in which case the digital frequency up-down converter block comes in handy. Una emptoris postulavit ut mos RF frequentiam convertentis pro suo 2.4G wireless video transmitter. Itaque initus frequency est 2.4GHz, ad output frequency est 600MHz, and the lowdown frequency is 1800MHz. Nos creavit specimen pro suis specificationibus. So I showed him a simple video that showed the 2.4G transmitter and 600Mhz receiver working correctly. Si similis postulationem, ut 1-3G frequentia initus et 300-700Mhz output, Contact us pro consuetudine solutionis.
FAQs
A RF frequency obstructionum downconverter (BDC) Video enim wireless transmitters est fabrica quae alta frequentia potest convertere ad range humili frequentia range.
Typice usus est in wireless video transfusor latus. eg,
- Ab 5.8G ad 2.4G descendit converter
- Ab 2.4G ad 1.2G descendit converter
- Ab 1.2G ad 600Mhz descendit converter
Hoc accidit quod frequentiae transmissionis wireless in multis regionibus vel regionibus restringuntur per leges et ordinationes locales.
Non licet in certa frequentia range.
Mutare frequentiam operating transfusor et accipientis, Descendit-conversio seu sursum-conversio non requiritur. Fac frequentia tradenda secundum leges locales et ordinationes.
Est etiam, ubi constituitur frequentia professionalis recipiendi, exempli gratia, inter 300-800Mhz *.
In order for the transmitter's frequency to be paired, Tille frequentia 1.2G transfusor reduci debet.
Haec omnia necessitatem habent usum frequentiae downconverti pro wireless videos tradendi.
Etiam, nostri professio fectum respondit, possumus facere id. Et, ante partum, test videbimus tibi ostendemus.

Quaeritur: If a signal of -25 dbm enter, what level has the coverterd output?
Et respondendum est,: 0 DBM
Quid est, LCC
In digital signum processui, a digital converter et, (DDC) conuerti fecerit digitized, Cohors limitata signo ad minus frequentiae signum in minori sampling rate ad simpliciorem reddere sequentes gradus radiophonicis. Servat modum quo minus notitia signo originis in flectendis promunturiis deperit risu processis in mathematicis. In input et output potest esse realis aut universa exempla annuit. Saepe in radio frequency DDC converts a rudis vel ad medium frequency signum in universa baseband.
Architecture
A DDC ex tribus subcomponents: recta digital synthesizer (dds), sparguntur saltu humili (LPF), and a down sampler (sparguntur in saltu humili poterit integrari). DDS generat sinuosum complexum in frequentia media (SI). Medium signa facit imaginum multiplicationem frequentia input conlocatum centrum in discrimen summa frequentia (quae sequitur e proprietatibus mobilibus frequentia Fourieriani transformatis). The low-pass filters pass the difference (i.e.. baseband) frequency cum summa frequency imaginem reddit, rejiciens, signum inde originale simulacrum complexus baseband. Posito tamen judicio prudenti IF et LPF, et universa baseband signum mathematice aequipolleant primis signum. In specie ejus nova, it can readily be down-sampled and is more convenient to many DSP algorithms. Quodvis idoneum low-passum sparguntur adhiberi possunt etiam PINUS, IIR, et CIC Filtra. Frequentissima electio est FIR filter pro low copia decimationis (minus quam decem) or a CIC filter followed by an FIR filter for larger down-sampling ratios.
Missa in DDC
Variae variationes in DDC utile sunt, quod addere cum inter tot feedback in signum dds. haec includit:
- Decision-directed carrier recovery phase-locked loops in which the I and Q are compared to the nearest ideal constellation point of a PSK signal, dant signum erroris percolantur et inde intravit dds
- A quo ansam Costas humilis IQ multiplicantur et transeunt percolantur partem BPSK / salute ansam tabellarius QPSK
implementation
DDCs sunt plerumque implemented in ratione agri vestit, porta vel programmable specialium applicationem integrated regreditur. Dum software est etiam possibile implementations, operatio dds, multiplicatores, and input stages of the low-pass filters all run at the sampling rate of the input data. Hic est notitia capta est directe ab Analog et digital commonly converters (ADCs) sampling ad decem aut centum MHz. CORDIC is an alternative to the use of multipliers in the implementation of digital down converters.
