Exempel på hur man kan använda DEMODULATION i en mening

• The degree of isochronous distortion, in data transmission, is the ratio of the absolute value of the maximum measured difference between the actual and the theoretical intervals separating any two significant instants of modulation (or demodulation), to the unit interval.
• In asynchronous serial communication data transmission, the ratio of (a) the absolute value of the maximum measured difference between the actual and theoretical intervals separating any significant instant of modulation (or demodulation) from the significant instant of the start element immediately preceding it to (b) the unit interval.
• Carrier power must be restored by the receiving station to permit demodulation, usually by means of a beat frequency oscillator (BFO).
• The receiver un-does these transformations in reverse order: demodulation, trellis decoding, error detection and correction, decompression.
• The turbo principle is generalized now by Claude Berrou and his lab team for the processing of various functions such as the demodulation, the detection or the equalization using a network of multiple convolution codes working in parallel with probabilistic feedback.
• Transmission system technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but it may also involve higher-layer protocol duties, for example, digitizing an analog signal, and data compression.
• In some color television standards, the color burst placed after every sync pulse on visible lines (as done in PAL and NTSC) is the pilot signal to indicate that there are color subcarriers present and allow synchronizing the phase of the local oscillator in the demodulation circuitry.
• If sufficient digital processing capacity is available, it is becoming commonplace to use this to generate the sinusoidal excitation via a DAC and possibly also perform the secondary demodulation via a multiplexed ADC.
• Since the optimal demodulation of full-response CPM already requires MLSE detection, using partial-response signaling requires little additional complexity, but can afford a comparatively smoother phase trajectory, and thus, even greater spectral efficiency.
• Modern vector network analyzers measure amplitude and phase of voltage traveling wave phasors using essentially the same circuit as that used for the demodulation of digitally modulated wireless signals.
• The FD1781 was designed for double density, but required external modulation and demodulation circuitry, so it could support MFM, M2FM, GCR or other double-density encodings.
• Lieben and his associates Eugen Reisz and Siegmund Strauss invented and produced a gas-filled triode – the first thermionic valve with a control grid that was designed specifically for amplification rather than demodulation of signals, and is a distant ancestor of the thyratron.
• The receiver generates the audio and video (AV) signals needed for television, and performs the following tasks: demodulation; error correction; MPEG transport stream demultiplexing; decompression; AV synchronization; and media reformatting to match what is optimal input for one's TV.
• A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal's carrier wave and the receiver's local oscillator for the purpose of coherent demodulation.
• Several methods were employed to generate an audible tone at the receiver: (1) a chopper, (2) a variable condensor with rotating plates (slope demodulation), (3) a tikker, (4) a separate heterodyne, and (5) the autodyne.
• The CIR resembles the carrier-to-noise ratio (CNR or C/N), which is the signal-to-noise ratio (SNR or S/N) of a modulated signal before demodulation.
• The carrier reference generated by the VCO of the carrier phased-locked loop was used to heterodyne the received signal to video, a process of synchronous demodulation.
• His work with Kyle Jamieson on SoftPHY systematically exploited demodulation confidence to improve bit rate adaptation, contention management, and parsimonious retransmissions for partial packet recovery, and his papers on sensor network protocols such as LEACH (with Wendi Heinzelman and Anantha Chandrakasan) and Spin were the first to consider overall system longevity as an important design goal, and have been cited many thousands of times by subsequent papers.
• The SPoD data, consisting of sequences of diffraction-limited images illuminated with varying linearly polarized light, were reconstructed with a deconvolution algorithm termed SPEED (sparsity penalty – enhanced estimation by demodulation).
