Abstract:
1. A Binary Amplitude Shift Keying (BASK) demodulator for providing a binary demodulated signal of a BASK modulated signal having a variable frequency carrier signal that is variable between a minimum and a maximum carrier frequency, the BASK demodulator comprising: a signal modifying circuit having input terminals and a signal modifying circuit output, wherein the signal modifying circuit includes, a low pass filter coupled to the signal modifying circuit for removing the signal frequency from the clipped scaled and biased alternating signal to provide a demodulated signal; an amplifier circuit coupled to the low pass filter to amplify the demodulated signal; and a signal shaping circuit coupled to the amplifier circuit for shaping the amplified demodulated signal and providing a shaped demodulated signal to an output of the demodulator to thereby provide the binary demodulated signal at the output of the demodulator.
