    Re: Multiplying with 11 using PIC

    Do not understand exactly what do you mean by sentence : "The PIC could switch in 1 of 2 or 3 PLL's for workable operating ranges."
    My idea is that PIC should detect the frequency frame in which PPL...

    Re: Multiplying with 11 using PIC

    Hi Richard , Hi Henrik
    You enormously help me in solving to approach to the task on the right way by conclusion that neither CCP or NCO should not lead to the solving of the problem.
    As one...

    Re: Multiplying with 11 using PIC

    Reply to mpgmike
    In private correspondence with Mr. Henrik the conclusion is that solution with NCO, and PIC working on 64MHz clock would not be the solution.
    Referring to your idea to measure time...

    Hi
    Anyone can help about the following task.
    Have to multiply input frequency by 11.
    The input frequency range is from 1 Hz to 1 MHz.
    Output frequency has to be from 11 Hz to 11 Mhz.
    Input...

    Re: Analog comparator in action

    Hi Henrik
    have just measured rise time - it is 2,5uSec (0 to 5 V positive edge) - with no distorsion on positive egde.
    signal under consideration - Quadrature signal, frequency = 30 KHz.
    Thank...
