Consider an FM broadcast that employs the pre-emphasis filter with frequency response
\(\rm H_{pe}(ω)=1+\frac{jω}{ω_0}\)
where ω0 = 104 rad/sec.
For the network shown in the figure to act as a corresponding de-emphasis filter, the appropriate pair(s) of (R, C) values is/are ________.
1
R = 1 kΩ, C = 0.1 μF
2
R = 2 kΩ, C = 1 μF
3
R = 1 kΩ, C = 2 μF
4
R = 2 kΩ, C = 0.5 μF
