A comment / question: Does it make sense to spend significant effort on computing an accurate SNR value? It might make sense for VSB and DVB-C / S, i cant tell. But i am sure that for DVB-T, it doesn't. A signal to noise ratio might be excellent but reception very poor due to several (short) echoes. For antenna optimization and comparison there (to my experience) are 2 useful values: signal strength (minor) and the raw bit error rate (major). The raw ber can be normalized to the maximum correctable ber and this would be a useful measure since this number tells about the real safety margin. Just my opinion Hartmut _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
