NAME
     testsig - generate some test signals

SYNOPSIS
     testsig (-s|-n|-p) (-f freq) (-t time) (-r time|-R time)  (-
     d) (-S sampfreq) file

DESCRIPTION
     testsig is a program to generate some test signals  directly
     into a speech file.

OPTIONS
     -I         Identify program name and version number.

     -s         Generate a sine wave. Default.

     -n         Generate white noise.

     -p         Generate pulse train.

     -ffreq     Specify frequency of sine wave.  Default 1000Hz.

     -ttime     Specify duration of signal.  Default 0.5 seconds.

     -rtime     Specify time to linearly  ramp  up  amplitude  to
                maximum at start and end. Default 0 seconds.

     -Rtime     Specify time to logarithmically ramp up amplitude
                to maximum at start and end. Default 0 seconds.

     -d         Differentiate output.

     -Ssampling_rate
                Specify  the  signal  sampling   rate.    Default
                20000Hz.

OUTPUT ITEMS
     SP   Test signal.

HISTORY
     type=      shows sine or noise waveform

     freq=      shows sine wave frequency

     time=      shows duration of signal

     ramp=      shows ramp time of signal

     differenced
                shows signal has been differentiated.

     samprate=  shows sampling rate.
