At our
current stage of research and development the ZHD transmitter shown
may be used as the common amplifier with the FM TPO specified above.
As development continues power output requirements may change:
Note: Official HD Radio system standards have not been adopted by the FCC at this time. The results of the calculations within this spreadsheet are based on the system parameters and combiner specifications in the table to the left and have a direct impact on the transmitter power requirements. These parameters may change as final rules are adopted by the FCC and as transmitter and combiner technology evolves.
