...it doesn't necessarily follow at all that 60 kW digital is less than 300
kW analog." Does anybody have a conversion formula?<<
The standard ratio of peak to average power (with standard black picture) is
1.68:1. Thus the 316 kW peak power previously licensed to WHDH was
equivalent to about 188 kW of average power.
I believe the doubling of DTV power was (in round figures) from 15 to 30 kW
ERP, not 30 to 60, and that the 30 has already been achieved.
