Amplitude modulation demodulation lab manual

LAB 7 AMPLITUDE MODULATION DEMODULATION Objectives: Understanding the principle of amplitude modulation (AM) and demodulation Understanding the waveforms of modulated and demodulated signals Observing the effects of the percent of modulation Designing amplitude modulator and demodulator using Simulink Theory. - LAB Manual Amplitude Modulation and Demodulation Experiment 5 Experiment 2 Figure 5. The Circuit of envelope detector and its signals. The ideal envelope detector is a circuit which consists of two parts, the first part is a rectifier to take the absolute value of the signal, while the second part is LPF to remove unwanted component.

Function Generator 2–HP A (FG2): The settings are: [Frequency: 10 kHz], [Amplitude: Vpp], [AM] and [Ext/Int Modulation]. Consult your lab instructor for manual setup instructions. Preset: Requiredsettings are stored in memory location[1] of the function generator. To access these settings press [Recall], select memory location [1] and press [Enter]. - LAB Manual Amplitude Modulation and Demodulation Experiment 5 Experiment 2 Modulation Index: In AM, this quantity, also called modulation depth, indicates by how much the modulated signal varies around its 'original' level. For AM, it relates to the variations in the carrier amplitude. AMPLITUDE MODULATION DEMODULATION Aim: 1. To generate amplitude modulated wave and determine the percentage modulation. 2. To Demodulate the modulated wave using envelope detector. Apparatus Required: Name of the Component/Equipment Specifications/Range Quantity Transistor (BC ) Ft=MHz Pd =1W Ic (max)=mA 1.
