We made Preliminary pages, Abstract and Chapter one of "design and construction of a digital frequency comparator" visible for everyone, then the complete material on "design and construction of a digital frequency comparator" is to be ordered for. Happy viewing!!!
A digital frequency comparator circuit comprising two counters connected to a circuit to be driven, in which one of the two counters which earlier issues an output signal is temporarily held, and both the counters are not cleared until the other counter subsequently issues an output signal, whereby an instability in the operation of the circuit to be driven is eliminated.
In this work, digital frequency comparator for oscillators indicates the result through a 7-segment display and a light-emitting diode (LED). When the frequency count of an oscillator is below ‘8,’ the corresponding LED remains turned off. As soon as the count reaches ‘8,’ the LED turns on and the 7-segment display shows ‘8.’
