Dear Sir,
I am building a custom block.
How to know the time t, in seconds, of how long the flow graph has started?
Says, I build a block of analog_sig_source_f.
Its work() function may involve a variable t (time) as below:
for ( int i=0; i < noutput_items; i++ ) {
out[i] = ampl * sin( 2 * PI * wave_freq * t )
}
I know we there is a built-in Signal Source block, but I write this to
illustrate what I need to do.
Regards,
activecat
