An $\mathrm{AC}$ voltage of frequency $2\mathrm{Hz}$ with $\mathrm{Vp}-\mathrm{p}100\mathrm{mV}$ signal needs to be amplified to drive a red or green $LED$ which is connected to limiting resistor $R_{\mathrm{L}}$. $R_{\mathrm{L}}$ will limit current through LED to maximum $20\mathrm{mA}$. Design the required amplifier circuit using Op-Amp TLV2741 to drive that LED. You need to determine suitable ${\mathrm{V}}_{cc},{\mathrm{R}}_{\mathrm{im}},{\mathrm{R}}_r$ and RL during construction of your circuit. The LED should blinking with frequency $2\mathrm{Hz}$ and the output voltage waveform across LED can be measured using ocsilloscope.
