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.
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
