3. To test the intermodulation distortion of an amplifier a signal $e_i=(4\cos (800?t)+$ $\cos (2000?t))mV$ is connected to its input. The measured frequency component of the output signal spectrum of the amplifier at $1\mathrm{kHz}$ is found to be $1\mathrm{V}$ while the frequency component at $600\mathrm{Hz}$ is found to be $1\mathrm{mV}$. If the input-output characteristics of the amplifier can be represented a $e_0=a_1{e}_i+a_2{e}_i^2$ use this data to find the numerical values of $a_1$ and $a_2$.
