Abstract
A Gaussian Frequency Shift Keying/Frequency Shift Keying (GFSK/FSK) modulation circuit implemented in a digital manner comprises a frequency divider for dividing frequency of an inputted clock signal to get a sampling signal, a buffer coupled to the frequency divider for storing inputted data, an integrator coupled to the buffer for processing integration according to the data outputted from the buffer, a first read only memory coupled to the integrator for transferring the data outputted from the integrator according to a cosine function, and a second read only memory coupled to the integrator for transferring the data outputted from the integrator according to a sine function.
