PWM Signal
in [Matlab]

From: Prashant Sandhi on 5 Oct 2009 09:00 Hi, I would like to know how can I generate a PWM signal in Simulink? Duty cycle=90% Amplitude = 5V Frequency= 15KHz

From: Prashant Sandhi on 5 Oct 2009 10:16 Hi, I am trying with pulse generator box but the output is not PWM. Can you tell me the values I can set for the block.

From: Sinem on 5 Oct 2009 10:34 Eventhough it's pretty self expressing... Here you go amplitude: 5V period: 1/15KHz pulse width: 90% "Prashant Sandhi" <sanddhi7(a)gmail.com> wrote in message <hacv33$7uo$1(a)fred.mathworks.com>... > Hi, > I am trying with pulse generator box but the output is not PWM. > Can you tell me the values I can set for the block. > > > > > "Arnaud Miege" <arnaud.miege(a)nospam.mathworks.co.uk> wrote in message <hacs59$frf$1(a)fred.mathworks.com>... > > > > "Prashant Sandhi" <sanddhi7(a)gmail.com> wrote in message > > news:hacql4$7a1$1(a)fred.mathworks.com... > > > Hi, > > > > > > I would like to know how can I generate a PWM signal in Simulink? > > > Duty cycle=90% > > > Amplitude = 5V > > > Frequency= 15KHz > > > > > > > use the pulse generator block > > http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/slref/pulsegenerator.html > > > > HTH, > > > > Arnaud > >
From: Prashant Sandhi on 5 Oct 2009 10:53 Well That is were I have problem in entering the value for period. 1/1500 = 0.0000636 number of samples it is giving error How can I give a 2D matrix value for this? 90% of pulse width means?
