Answer to Question #205975 in Electrical Engineering for wea

Question

For high -pass active filter with corner frequency 8 kHz, then R and C are: 

Select one : 

a. 2.5kΩ ,7.9557nF 

b. 2 kΩ ,7.9557nF 

c. 5kΩ ,7.9557nF 

d. 10kΩ ,7.9557nF

e. 1kΩ ,7.9557nF

Answer 1

$\\\nu=\frac{1}{2\pi RC}\to\frac{1}{2\cdot3.14\cdot2500\cdot7.9557\cdot10^{-9}}\approx8000\ (Hz)$ . So,

a. 2.5kΩ ,7.9557nF. Answer
