FSK Modulators using IC 555
FSK means Frequency Shift Keying. It’s one of the Modulation Scheme used to Transmit Digital Data using High Frequency carrier signal. In this Modulation Scheme bit 1 is transmitted using one carrier signal and bit 0 is transmitted using another carrier signal like· Bit 1 (logic high) is Transmitted using Carrier Frequency Fc1· Bit 0 (logic low) is Transmitted using Carrier Frequency Fc2It means Series of bits (bit stream) are transmitted with two different carrier signals used for bit 1 and bit 0.
