| Real[:] | u_buf | | Signal for which FFT shall be computed; (size(u_buf,1) MUST be EVEN and should be an integer multiple of 2,3,5, that is size(u_buf,1) = 2^a*3^b*5^c, with a,b,c Integer >= 0) |
| Integer | nf | | Number of frequency points that shall be returned in amplitudes and phases (typically: nf = max(1,min(integer(ceil(f_max/f_resolution))+1,nf_max))); the maximal possible value is nf_Max=div(size(u_buf,1),2)+1) |
| Integer | iTick | | Number of sample points that have been stored in u_buf |
| Modelica.Units.SI.Time | Ts | | Sample period of FFT |
| Boolean | pre_periods_ok | | Previous value of periods_ok |
| String | instanceName | "???" | |
