ahcheong_ray Posted August 17, 2005 Report Share Posted August 17, 2005 what is the different btw A/D and PWM???is it same or different??? Quote Link to comment Share on other sites More sharing options...
izach Posted August 17, 2005 Report Share Posted August 17, 2005 a/d = analogue to digital therefore to convert analogue to digital one would sample the analogue signal a given number of times each time a sample is takena digital byte is recorded represented by ones and zero's depending on the resolution this word could be 8 bits or 14 bits etc long this would then be supplied at the output either parrallel or serial.pwm=pulse width modulation this would be an output from say a microprocessorwhere a square wave is generated with a varying on time and a varying off time but the amplitude of the wave remains the sames Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted August 22, 2005 Report Share Posted August 22, 2005 A/D is a conversion process which consists of sampling ,quantization and coding while in the end comes a modulation technique like PWM. Quote Link to comment Share on other sites More sharing options...
