One of the key questions regarding vocoding relates to speech quality As alluded to earlier, MOS is a popular method to assess subjective quality measures Other methods also exist For example, Table 2-3 depicts a number of popular vocoder technologies16 The second column of this table contains typical mean values of auditory distance (AD), as calculated by the Measuring Normalized Block (MNB) Structure 2, defined by S Voran17 The third column contains typical mean values of AD after transformation by a logistic function, as defined in those same documents Note that larger values of AD indicate that the speech is farther (in the perceptual sense) from the original speech Larger values of L(AD)18 indicate a higher-estimated perceived speech quality Although these measures are not identical to the MOS used by carriers, they do provide another view of the quality of the coding methods split pdf using c#: Simply Split PDF Document to Multiple Files in C#, VB.NET - E-iceblue c# get thumbnail of pdf GitHub - lmorelato/ pdf - thumbnail : C# tool for generating image ...

This is a 500 pages concise technical eBook available in PDF , ePub (iPad), and Mobi ... Figure 1-4 FM modulation waveform the same frequency Problematically, however, frequency drift or lack of selectivity may cause one station or signal to be suddenly overtaken by another on an adjacent channel Frequency drift typically constituted a problem on very old or inexpensive receivers, while inadequate selectivity may plague any tuner Frequency modulation is used on the FM broadcast band between 88 and 108 MHz as well as in the VHF and UHF bands for both public service and amateur radio operators removed because it is the sidebands that provide the actual meaningful content of material, within the modulation envelope In order to make SSB even more efficient, one of these two sidebands is removed by a bandpass So the intelligence is preserved with SSB and it becomes a more efficient use of radio spectrum energy It provides almost 9 Decibels (dBs) of signal gain over an amplitude modulated signal that includes an RF carrier of the same power level! As the final RF amplification is now concentrated in a single sideband, the effective power output is greater than in normal AM (the carrier and redundant sideband account for well over half of the power output of an AM transmitter) Though SSB uses substantially less bandwidth and power, it cannot be demodulated by a simple envelope detector like standard AM SSB was pioneered by telephone companies in the 1930s for use over long-distance lines, as part of a technique known as frequency-division multiplexing (FDM) This enabled many voice channels to be sent down a single physical circuit The use of SSB meant that the channels could be spaced (usually) just 4000 Hz apart, while offering a speech bandwidth of nominally 300 3400 Hz Amateur radio operators began to experiment with the method seriously after World War II It has become a de facto standard for long-distance voice radio transmissions since then. Single sideband modulation (SSB) is a refinement upon amplitude modulation, which was designed to be more efficient in its use of electrical power and spectrum bandwidth Single sideband modulation avoids this bandwidth doubling, and the power wasted on a carrier, but the cost of some added complexity The balanced modulator is the most popular method of producing a single sideband modulated signal The balanced modulator provides the sidebands of energy that exist on either side of the carrier frequency but eliminates the RF carrier, see Figure 1-5 The carrier is Speech Coder Original speech (No coding) ITU Rec G711, 64-Kbps m-law PCM ITU Rec G726, 32-Kbps m-law ADPCM ITU Rec G729, 8-Kbps CS-CELP ITU Rec G728, 16-Kbps LD-CELP ITU Rec G7231, 64-Kbps multipulse excitation with a maximum likelihood quantizer (MP-MPQ) GSM, (European Cellular System) 13-Kbps regular pulse excitation with long-term prediction (RPE-LTP) Mixed-excitation linear predictive (MELP) vocoder, proposed US Federal Standard, 24 Kbps US Federal Standard 1015, 24-Kbps LPC-10e AD 000 086 162 NA 182 NA L(AD) 096 090 081 NA 077 NA Single Sideband Suppressed Carrier (SSB-SC) modulation was the basis for all long-distance telephone communications up until the last decade It was called L carrier It consisted of groups of telephone conversations modulated on upper and/or lower sidebands of contiguous suppressed carriers The groupings and sideband orientations (USB, LSB) supported hundreds and thousands of individual telephone conversations Single sideband communications are used by amateur radio operators and government, and utility stations primarily in the shortwave bands for long-distance communications c# make thumbnail of pdf Generate thumbnail image for office document in c# - MSDN - Microsoft
