From 65a1b98552d7c6a93aedfb7c9b5d83f9038227cb Mon Sep 17 00:00:00 2001 From: Miller Puckette Date: Sat, 31 Dec 2005 00:59:49 +0000 Subject: Added about 64 files that I hadn't realized weren't in the CVS repository. Threw in pd/portaudio/pa_win_wdmks for good measure, although I haven't tried compiling that in yet (no windoze machine handy today). svn path=/trunk/; revision=4316 --- pd/doc/3.audio.examples/J03.pulse.width.mod.pd | 48 ++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 pd/doc/3.audio.examples/J03.pulse.width.mod.pd (limited to 'pd/doc/3.audio.examples/J03.pulse.width.mod.pd') diff --git a/pd/doc/3.audio.examples/J03.pulse.width.mod.pd b/pd/doc/3.audio.examples/J03.pulse.width.mod.pd new file mode 100644 index 00000000..06301686 --- /dev/null +++ b/pd/doc/3.audio.examples/J03.pulse.width.mod.pd @@ -0,0 +1,48 @@ +#N canvas 46 315 784 514 12; +#X floatatom 95 64 0 0 0 0 - - -; +#N canvas 0 0 450 300 graph1 0; +#X array \$0-difference 882 float 0; +#X coords 0 1.02 882 -1.02 200 130 1; +#X restore 565 325 graph; +#X text 81 39 frequency; +#N canvas 0 0 450 300 graph1 0; +#X array \$0-phasor1 882 float 0; +#X coords 0 1.02 882 -1.02 200 130 1; +#X restore 565 24 graph; +#X text 57 9 CLASSICAL PULSE WIDTH MODULATION; +#X obj 111 156 phasor~ 0; +#X obj 111 132 + 0.2; +#X obj 95 206 -~; +#N canvas 0 0 450 300 graph1 0; +#X array \$0-phasor2 882 float 0; +#X coords 0 1.02 882 -1.02 200 130 1; +#X restore 565 176 graph; +#X text 24 314 This patch demonstrates pulse width modulation \, which +is accomplished simply by subtracting two sawtooth waves at a varying +phase difference.
