Final answer:
To find G_linear, substitute the value of G_dB into the expression and evaluate it using the properties of exponents and logarithms.
Step-by-step explanation:
The given expression is G_dB = G1dB - G2dB + 30dB. To find G_linear, which is equal to 10^(G_dB/10), we need to substitute the value of G_dB into the expression and evaluate it.
G_linear = 10^(G_dB/10) = 10^((G1dB - G2dB + 30dB)/10)
Now, we can simplify it further using the properties of exponents, and apply the rules of logarithms if necessary to solve the equation.
