For the following system: R(s) Y(s), G1 G2 G3 + G4 G6 G5 Y(s) the transmittance gains are as follows: R(s) Solve the transfer function G1 = G2 G3 G4 1 1 4. Gs = Go = 2 Ensure the final output is a fully expanded polynomial, and of the form When writing your fraction you can use the following template: (s^2+3s^1)/(4s^3+2s^2+s+1). Note do not write multiplications and the divide sign is the slash: /
