I think there is an example to do exactly this in Python but you can also do it in GRC:On Tue, Jun 21, 2011 at 3:28 PM, John Ackermann N8UR <address@hidden> wrote:In GRC I would like to combine the outputs of several NBFM modulator blocks to drive a USRP sink. The idea is to output several discrete channels within the USRP transmit bandwidth, e.g., three signal channels at -30 kHz, 0 kHz, and +30 kHz offset from the USRP tune frequency.
I'd appreciate suggestions on how best to accomplish this.
(1) multiply the output of each modulator with a complex number corresponding to the offset from center
(2) add all channels together
