A particular amplifier has a voltage transfer function T(s)=\frac{10 s^{2}}{\left(1+\frac{s}{10}\right)\left(1+\frac{s}{100}\right)\left(1+\frac{s}{10^{6}}\right)} Find the poles and zeros. Sketch the magnitude of the gain in dB versus frequency on a logarithmic scale. Estimate the gain at 10^0, 10³, 10^5, and10^7 rad/s.
