| 1 .TH STEP 1 "1 September 1993" | |
| 2 | |
| 3 .SH NAME | |
| 4 step \- generate a step waveform. | |
| 5 | |
| 6 .SH SYNTAX | |
| 7 step [options] | |
| 8 | |
| 9 .SH DESCRIPTION | |
| 10 Generate a step up or down of given amplitude at a given shift from the origin | |
| 11 (start of waveform), and write the resulting waveform on the stdout in the | |
| 12 given datatype. | |
| 13 | |
| 14 .SH OPTIONS | |
| 15 | |
| 16 1. shift | |
| 17 | |
| 18 The position of the step (up or down) relative to the start of the waveform. | |
| 19 The shift can be in samples (no units) or can take time units | |
| 20 (using the samplerate option). | |
| 21 | |
| 22 2. amplitude | |
| 23 | |
| 24 The height of the step. | |
| 25 | |
| 26 3. polarity | |
| 27 | |
| 28 The direction of the step: up (zero before the step and `amplitude' after) | |
| 29 or down (`amplitude' before the step and zero after). | |
| 30 | |
| 31 4. duration | |
| 32 | |
| 33 The duration of the output wave, including the shift to the step. | |
| 34 The duration can be in samples (no units) or can take time units | |
| 35 (using the samplerate option). | |
| 36 | |
| 37 5. type | |
| 38 | |
| 39 The output datatype. This may be any of: char, short, int, float, double, | |
| 40 ascii (meaning one ascii number per line). | |
