Calculate the lower and upper cutoff frequencies of the bandpass filter circuit in Fig.
FIG.
Refer to the circuit diagram shown Fig. 11.59 in the textbook.
Write the expression for the lower cutoff frequency of the first-order bandpass filter.
Substitute for , and for to calculate .
Hence, the lower cutoff frequency of the bandpass filter is .
Write the expression for the higher cutoff frequency of the first-order bandpass filter.
Substitute for , and for to calculate .
Hence, the upper cutoff frequency of the bandpass filter is .
