When you talk about "constellation diagrams" I guess that you are an expert and I don't interpret your first question as "what is a QPSK demodulator" but as "where can I get more information about it" ;-) The best page I have seen so far is this one: http://www.geocities.com/buenavista18/ Ralf. -----Original Message----- From: Pascal Vollmer [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 26, 2001 11:16 To: 'Linux TV' Subject: [linux-dvb] Another question concerning FE Hi, I am rather new to this list. Can anyone tell me what is the QPSK demodulator chip used, where to get datasheets and if I/Q-samples are available from the chip in order to show a constellation diagram and to evaluate the signal quality from it.
