Using 741 op amp, design a suitable circuit to generate Binary Phase Shift Keyiing(BFSK) modulator. Design should perform in such a way that the BFSK output should contain a frequency of f1=2kHz when message signal is low and f2 =4kHz when the message signal is high. Take the frequency of message signal as 200Hz. Draw the clear circuit diagram and calculate the values of resistors and capacitors used.
