DSB-SC Demodulation using matlab

  1. 1. DSB-SC DEMODULATION ‫االسم‬:‫داود‬ ‫سلمان‬ ‫افراح‬ -IT ‫المرحله‬:‫الثالثه‬– ‫االتصاالت‬ ‫مختبر‬
  2. 2.  Demodulation is done by multiplying the DSB-SC signal with the carrier signal. For demodulation, the modulation oscillator's frequency and phase must be exactly the same as the demodulation oscillator's otherwise, distortion and/or attenuation will occur. DSB-SC can be demodulated if modulation index is less than unity. Demodulation
  3. 3.  Designing the DSB-SC demodulation circuit with the matlab program requires to design the DSB-SC modulation circuit first, design DSB-SC demodulation circuit second, then connect the output of the modulator circuit to the input of the demodulator circuit. Choose the components from the Simulink Library Browser as shown in the following figures: DSB-SC Demodulation Circuit
