Abstract: This paper explores the practical application of diverse digital modulation techniques through FPGA implementation, providing a comprehensive overview of the design specifics and logic resource utilization. The choice of FPGA for implementation stems from its advantageous features in terms of performance, power efficiency, and configurability. Digital modulation serves as the mechanism for transmitting a digital bit stream from the transmitter to the receiver across analog channels. In this process, the information signal alters one or more carrier parameters, employing shift keying techniques. The study focuses on the implementation of two primary modulation techniques: Amplitude Shift Keying (ASK) modulation and Quadrature Amplitude Modulation (QAM). The entire simulation is conducted using VERILOG Hardware Descriptive Language on ModelSim and Xilinx ISE 14.5 PlanAhead, emphasizing practical applications and real-world viability.
