outsig=expchirp(L,fstart,fend)
expchirp(L,fstart,fend) computes an exponential chirp of length L starting at frequency fstart and ending at frequency fend. The freqencies are assumed to be normalized to the Nyquist frequency.
expchirp takes the following parameters at the end of the line of input arguments:
| 'fs',fs | Use a sampling frequency of fs Hz. If this option is specified, fstart and fend will be measured in Hz. |
| 'phi',phi | Starting phase of the chirp. Default value is 0. |
| 'fc',fc | Shift the chirp by fc in frequency. Default values is 0. |
| 'ramp',r | Apply fade-in and fade out ramps on the first and last r samples. |
