How do you justify your assertion that phase errors of 1 degree are OK but 4 degrees are not ? > Phase shifts changing with frequency also translate into amplitude > errors when the phase shifter chains are summed. Of course. And it's quite easy to quantify these amplitude errors, and their effect on the final result. > Not having to use analogue now makes this easily possible with a > good design, and at reasonable mips cost. Why accept less? There is indeed no reason to accept less than what is required, but accepting that doesn't answer the question of how much accuracy is actually required. You tell me that 1 degree is OK and 4 is not, but so far I haven't seen any analysis supporting this assertion.
