Outputs ASCII file of band passed time history. Graphic display of input time history as well as band passed output time history is also provided. |
| 8 | FFT | Takes one directional equally sampled ASCII time history file as input and outputs Fourier magnitude of time history in ASCII format. Graphic display of input time history and output FFT magnitude is also provided. |
| 9 | INSCOR | Takes equally sampled ASCII acceleration time history file as input. Takes natural frequency and damping of sensor as input through terminal. Performs instrument correction of the input file and outputs the ASCII corrected acceleration time history file. Graphic display of input time history as well as instrument corrected output time history is also provided. |
| 10 | WNOISE | Generates synchronous noise (a white noise whose Fourier magnitude is exact one) of duration and sampling rate to be taken through terminal. Graphic display of generated time history is also provided |
| 11 | BASECOR | Takes equally sampled ASCII time history file as input. Takes least square line of the history as baseline (x axis) and outputs ASCII file with new base line (rotational components not considered). Graphic display of input time history as well as baseline corrected output time history is also provided. |
| 12 | NONLIN | Takes unequally sampled ASCII time history file as input. Outputs linearly interpolated equally sampled time history file at sampling rate to be given through terminal. |

| 17 | PROC1 | Takes digitized files of records of SMA 1 performed on digitizing table of DEQ and converts them on unequally spaced uncorrected accelerogram |
| 18 | ALINT | Performs linear interpolation to increase sampling rate of an equally spaced ASCII time history file. |
| 19 | INPO1 | Performs band limited interpolation of equally spaced ASCII time history file such that values of original samples do not change and new samples are determined in between original samples such that frequency contents of original sequence are maintained |
| 20 | INPO2 | Performs band limited interpolation of equally spaced ASCII time history file. However, values of original samples are not kept and all the new samples are determined such that frequency contents of original sequence are maintained. |
