    Default Re: NCO Calculator

    Hi mpgmike:

    At the risk of seeming like a troll, may I make a couple suggestions, just in case you ever revisit your NCO Calc program, please?

    (1) Allow entry of NCO Frequencies such as 8388608-Hz without rounding.
    (2) Correct the NCO bit width constant (2097152) in your calculations.
    (3) Display the NCO frequency resolution.
    (4) Display the output frequency error.

    I whipped up a quick spreadsheet to highlight the calculation problems I'm experiencing. Your NCO Calc app' introduces errors by rounding the NCO frequency and by using the incorrect NCO bit width constant in your calculations.

    Have fun. Best wishes. Cheerful regards, Mike, K8LH
