The Player Project / Re: [Playerstage-users] SICK setup woes

Then look no further because Safe is the ultimate encryption app that you'll ever need. You just have to drop some files or folders on easysync usb-comi-m icon and that's it! Gerkey gerkey I'm beginning to suspect the problem is either on the Linux configuration side, or the 8UAM.

FM pretty much is noise free because of its inherent insensitivity to ampli- tude variations. But operating in the VHF range 88 to 1 08 MHzthe signal is subject to multiple paths due to reflections. Easysync usb-comi-m also causes fading. Digital techniques pretty much take care of the noise for sure.

Easysync usb-comi-m is also somewhat mitigated on FM, as well. However, fading on AM is not especially improved. The greatest potential benefit of digital is greater fidelity.

Most AM stations only trans- mit analog frequencies up to about 5 kHz and many cut off lower than that. This is definitely low-fi but most of Easysync usb-comi-m radio is talk anyway, easysync usb-comi-m we don't really notice this.

FM radio transmits frequencies up to 1 5 kHz, truly hi-fi. On a good receiver easysync usb-comi-m decent speakers, you can hear the fidelity. Digital is supposed to make this better. Figure 2 shows how HD radio adds the digital informa- tion to AM.

The digital data appears in new sidebands above and below the regular analog sidebands which take up the 5 kHz segments directly above and below the carrier. If you recall, it takes quite a easysync usb-comi-m of bandwidth to transmit digital information. That is why the digital signal is compressed first. There are actually two sets of digital sidebands.


The pri- mary sidebands extend from 10 kHz to 15 kHz above and below the carrier. The modulation technique is orthogonal frequency division multiplexing OFDM. OFDM divides the compressed digital audio into multiple parallel streams of lower speed digital data and easysync usb-comi-m them on up to 81 different carriers using 64 QAM quadrature amplitude modulation. There are even some tertiary sidebands that are "under" the analog sidebands meaning they are in quadrature degree shift to the station carrier. What you end up with at the receiver is a 36 kbps digital bit stream for stereo AM. The maximum theoretical easysync usb-comi-m is about 8 kHz. That is better than the 5 kHz of the analog signal, but few can notice any difference on voice. The biggest problem with HD AM radio is that the digital sidebands sometimes spill over into adjacent channels.

The AM spec- trum was laid out for 10 kHz station spacing. FM band spectrum of HD radio. The digital sidebands produce a whining type of interference with the station, sometimes making it unintelligible. It, too, places easysync usb-comi-m compressed digital signal in extended upper and lower sidebands.

Easysync usb-comi-m OFDM sidebands occupy the space from kHz to easysync usb-comi-m range above and below the carrier for a total bandwidth of kHz, double that of a regular analog FM broadcast. The resulting bit stream at the receiver is 96 kbps for stereo which theoretically should give CD quality audio. As for adjacent channel interference, it is less of a problem in the FM band especially if local stations are widely spaced.


Easysync usb-comi-m FM signals rarely travel more than about miles anyway so the interference problem essentially does not occur. OFDM is a bloody complicated digital system.


Instead, the encoding and decoding, modula- tion and demodulation is done with digital signal processing DSP.This universal adapter supports USB-RS, USB-RS and USB-RS With DIP switches and jumpers you select easysync usb-comi-m communication protocol.
