To provide a low-cost FSK (Frequency Shift Keying) modulation / demodulation device in a needle-reading device or the like equipped with a 400 MHz-band specified low power radio.SOLUTION: The oscillation circuit 1101 generates the reference clock c3 which is m times as large as the desired ...
5FREQUENCY SHIFT KEYING (FSK) MODULATION, DEMODULATION, AND PERFORMANCE 5.1 INTRODUCTION Frequency shift keying (FSK) modulation is a robust modulation, in that, phase coherence is not required to achieve near … - Selection from Digital Communications
FPGA based generalized architecture for Modulation and Demodulation Techniques Here we design a modulator-demodulator circuit which can execute different modulation schemes like- AM, ASK, BPSK, FSK & QPSK. Both the LUT based implementation and complete VHDL based implementation have done by using digita...
The theory of FSK Modulation and Demodulation FSK modulation is one modulation mode to translate the information by changing the frequency of the carrier. It is one digital modulation technology that translates the information by using the base band digital signal discrete values to change the carrier...
The algorithm is designed for both modulation and demodulation. In the modulation part, it is just simple logic to create different phrases and different frequencies of sinusoidal waves. But in demodulation, based on the frequency it can detect ASK (Amplitude Shift Keying) or FSK (Frequency Shift...
Using MATLAB Simulink simulation tools were established FSK modulation model coherent, as well as simulation models were tested, the results show that the simulation results agreed with the basic theory. Keywords:FSK ; MATLAB ; simulation ; modulation; demodulation...
