PULSE WIDTH MODULATIONA modulation technique in which pulse of the carrier signal is changed in accordance with the amplitude comparison of message signal with carrier signal. Code ExplanationA message signal of particular frequency is defined then carrier signal of the form sawtooth is defined. Now desired result is obtained by comparing the amplitudes of message and carrier signals i.e if message signal is less than carrier signal pulse of output signal is zero otherwise pulse of the output signal is one.
