+
+.SH NAME
+ptrain  \-  generate a pulse train of binary shorts.
+
+.SH SYNTAX 
+ptrain  [arguments]  [file]
+
+
+.SH DESCRIPTION
+Generate periods of a pulse train in binary 2-byte numbers to the given
+waveform duration.
+A period in samples is computed (using the "period" option in samples or in
+time units, in which case the period also depends upon the given samplerate),
+and "width" samples at the start of every period are output with the given
+"amplitude", the remaining samples in the period having zero amplitude.
+The pulse amplitude is the pulse height above the zero level, which is
+set by the offset option. The offset is "0" by default so that pulses
+of any given amplitude are non-negative by default.
+
+The default output is 12 periods of an 8ms pulse train at 20KHz (ie with 160
+samples per period), with pulse width 4 samples and pulse amplitude 1024.
+
+If a filename argument is given, then the period of the output pulse train
+is taken from the file. Binary shorts read from the file are successive
+periods in samples, and periods are output until the file is empty.
+This enables pulse trains with modulated periods.
+
+.SH EXAMPLES
+
+
+1. A pulse train with period 100 samples and pulse width 1 sample:
+
+ptrain period=100p width=1p
+
+2. A pulse train with period 8ms at 20KHz and pulse width 4 samples
+
+ptrain period=8ms samplerate=20000Hz width=4p
