Software Defined Radio (SDR) has gained much interest in recent years due to the advancements in FPGA technology. FPGA provides the capability of programming Analog Components (Mixers, PLL, Filters etc...) which were traditionally implemented in hardware. In this paper digital functional blocks that need to be programmed in FPGA core are designed and simulated using Matlab for Amplitude demodulation for Double Side Band (DSB) with carrier, Double Side Band with Suppressed Carrier (DSB-SC) and Single Side Band with Suppressed Carrier (SSB-SC). Sampling frequency of 4MHz is selected to ensure that sampling rate is greater than twice of maximum commercially available AM carrier frequency (of 1720 kHz) and carrier frequency of 610 kHz is used for simulations. This simulation result concludes the proper operation of the design.
