Plantronics entered the multimedia headset market in 1999 with the release of the HS1 and the DSP-500 headsets, the latter featuring a built-in digital signal processing card. In 2002, Plantronics and Microsoft created the headset for the Xbox Communicator, the first headset to enable voice communication with Xbox Live . [ 13 ]
If the pulse shaping filter is rectangular in the time domain, the result is an unlimited spectrum. In many base band communication systems the pulse shaping filter is implicitly a boxcar filter. Its Fourier transform is of the form sin(x)/x , and has significant signal power at frequencies higher than symbol rate.
In most switching systems one pulse is used for the digit 1, two pulses for 2, and so on, with ten pulses for the digit 0; this makes the code unary, excepting the digit 0. Exceptions to this are Sweden, with one pulse for 0, two pulses for 1, and so on, and New Zealand, with ten pulses for 0, nine pulses for 1, etc. Oslo, the capital city of ...
[5] [33] While two channels (stereo) is the most common format, systems can support up to 8 audio channels (7.1 surround) [2] [3] or more. Common sampling frequencies are 48 kHz as used with DVD format videos, or 44.1 kHz as used in CDs. Sampling frequencies of 96 kHz or 192 kHz can be used on some equipment, but the benefits have been debated.
While pulse compression can ensure good SNR and fine range resolution in the same time, digital signal processing in such a system can be difficult to implement because of the high instantaneous bandwidth of the waveform (can be hundreds of megahertz or even exceed 1 GHz.) Stretch Processing is a technique for matched filtering of wideband ...
