2. (1pt) The corner frequency of the lowpass filter is defined as the frequency at which the magnitude of the gain

is 0.707 (1/√2) of the DC gain (@-0). This is also called the half power frequency (since 0.707²=0.5), and

the-3dB frequency since 20log(0707) --3dB. Find, in terms of R and C, the frequency in both Hz and in

rad/s at which the voltage gain is 0.707 of the DC gain (-0).
