${f_{out}} \cong \frac{{1.2\;}}{{4{R_1}{C_1}}}Hz,\;\;{f_L} = \pm \frac{{4{f_{out}}}}{V}Hz$

TuteeHUB · Answer

${f_{out}} \cong \frac{{1.2\;}}{{{R_1}{C_1}}}Hz,\;{f_L} = \pm \frac{{4{f_{out}}}}{V}Hz$

TuteeHUB · Answer

${f_{out}} \cong \frac{{1.2\;}}{{4{R_1}{C_1}}}Hz,\;{f_L} = \pm \frac{{8{f_{out}}}}{V}Hz$
