    Creating 150khz sine wave

    Makes sense I guess. I might try an AD9833 DDS module from Analog Devices which is a bit low spec compared to the AD9851 in the DDS-60 but I need 150 khz anyways so it doesn't really matter. Read that it should be able to do basic B-FSK with the two internal frequency registers from the...

    Creating 150khz sine wave

    Hey Paul, A shift of 0.5 khz is what I am aiming for. So between the space and mark frequency a shift of 500 Hz. I understand what you are saying, I am just trying to wonder if there is a simpler way to produce the same signal. Kind of spoilt from using high speed DACs and ADCs in moderns SDRs...

    Creating 150khz sine wave

    Sorry I did not mean Amplitude modulation. I mean B-FSK modulation at 150 khz frequency :P I am a radio guy yet I mix frequencies and modulation :P

    Creating 150khz sine wave

    Hey Mark, I don't have specific signal requirements per say. My goal is to make an AM transmission with minimum parts added which uses B-FSK at 600 BPS. I guess I can add filtering externally if the signal is too dirty to transmit. At such low frequencies the transmission will be so inefficient...

    The signal being at 150 Khz that is.

    Creating 150khz sine wave

    Hey Paul thank you for replying. Sounds like a fairly daunting task. What would be the simplest solution to generate a BFSK signal at 600 BPS from the Teensy 3.6 considering that I am willing add some cheap single module ? Also is it possible to do it easier on some other teensy revision (4.1 ??)

    Creating 150khz sine wave

    I understand. Is there anyway to do it natively on the teensy ? maybe with some LPF attached ?

    Creating 150khz sine wave

    Hello everybody, I am trying to produce a 150 khz sine wave from the teensy 3.6 I understand that this is far greater than the DAC speed according to the spec sheet. I was wondering if this is possible to do with the timers on the teensy 3.6 and has anybody tried ? My final application is to...
