This method adds watermark text under pdf content /// </summary> A radio signal is transmitted through the ionosphere and is picked up by the antenna in your radio receiver The antenna is fed to an RF amplifier and usually an intermediate amplifier or IF amplifier and then on to a detector of some sort depending upon the type of receiver you are using From the detector, the resultant audio signal is amplified and sent to a loudspeaker for listening Figure 1-6 illustrates a block diagram of a typical AM radio receiver The antenna is sent to the RF amplifier The mixer is fed by both the local oscillator and the RF amplifier The signal from the mixer is sent to a bandpass filter and then on to the first IF amplifier The first IF amplifier is next sent to the detector and then on to the final audio amplifier stage which drives the speaker The illustration depicted in Figure 1-7 shows a typical FM receiver block diagram The antenna feeds the RF amplifier stage Both the RF amplifier and local oscillator are fed into the mixer The signal from the mixer is next sent to the IF amplifier stage From the IF amplifier stage the signal is next sent to the FM demodulator section, which feeds the signal to the voltage amplifier and then the signal is fed to the final audio amplifier stage and on to the speaker Note the feedback path between, ie the AGC or automatic frequency control from the FM demodulator back to Speech analysis is also called digital speech encoding (or coding), and speech synthesis is also called speech decoding The objective of any speechcoding scheme is to produce a string of voice codes of minimum data rate, so that a synthesizer can reconstruct an accurate facsimile of the original speech in an effective manner while optimizing the transmission (or storage) medium Figure 2-3 depicts a generic audio encoder19 The waveform methods discussed earlier relate to a time-domain (signal amplitude versus time) representation of the speech signal Vocoding looks at the signal in the frequency domain; the spectrum represents the frequency distribution of energy present in speech over a period of time Frequency-domain coders attempt to produce code of minimum data rate by exploiting the resonant characteristics of the vocal tract A lot of information can be extracted and exploited in the speech spectrum Different Table 1-2 (F) 3-ferrite beads (see front-end)- run wire through beads Q1,Q2,Q3 Dual Gate MOSFET 40673 or ECG222 Q4,Q5 nJFET MPF102 add watermark image to pdf using itextsharp c# Add watermark to pdf file created at run time using itextsharp ...
