Where fo=free running frequency And V=(+V)-(-V)Volts And

From above equation the lock range increases with an increase in input voltage but decrease with increase in supply voltage. The two inputs to the phase detector allows direct coupling of an input signal, provided that there is no dc voltage difference between the pins and the dc resistances seen from pins 2 and 3 are equal.

DATA CONVERTER

Fig 2.15: Application of A/D and D/A converters

Fig 2.15 shows the application of A/D and D/A converters. The transducer circuit will gives an analog signal. This signal is transmitted through the LPF circuit to avoid higher components, and then the signal is sampled at twice the frequency of the signal to avoid the overlapping. The output of the sampling circuit is applied to A/D converter where the samples are converted into binary data i.e. 0’s and 1’s. Like this the analog data converted into digital data.
