May 11, 2008 · First off, yes, I know there are other tutorials on how to watermark PDF's with iTextSharp. Unfortunately none of them showed me exactly what I ... provides the selectivity to filter out the desired narrow band transmission The 6N2 receiver operates on two of the most popular VHF amateur radio bands The 6N2 VHF amateur radio receiver receives both the 6-meter ham band and the 2-meter ham bands, and you can select the band with a band-switch To help you visualize the relationship between frequency and wavelength, take a look at the diagram shown in Figure 12-4 If the speed of a wave (meters per second) is divided by the number of waves that pass a given point (cycles per second), the seconds cancel and you obtain the wavelength = meters per cycle The speed of radio waves is approximately 300,000,000 meters per second If the frequency is 50 to 54 MHz, the wavelength becomes 300,000,000/50,000,000 or 6 meters So for the 2-meter band, which is approximately 150 MHz, the wavelength becomes 300,000,000/150,000,000 or 2 meters The actual bands are: 2-meter band which covers 144 MHz to 148 MHz, and the 6-meter band which covers 50 MHz to 54 MHz The 6N2 dual band VHF receiver is composed of four major blocks, ie blocks 1 through 4 It is a bit easier to follow how the receiver works if we break it down into smaller defined blocks, see Figure 12-5 The heart of the receiver is the integrated circuit at U1, an almost complete FM receiver on-a-chip The FM receiver chip only requires timing components, a crystal and RF tuning components, a filter The output of the FM radio chip is sent to the audio amplifier chip at U2 Power for the receiver is regulated via the regulator chip at U3 add watermark to pdf using itextsharp c# watermark text in all the pdf pages of existing pdf - C# Corner
