• amplifiers have an enter impedance and output impedance. components of alerts like microphones have a intense impedance and extremely low sign out placed (milivolts). audio gadget (output tranducers) require extra skill (modern-day). a chain of ampl…

• ..but then what? Then, bring everything to the LHS leaving a zero on RHS, and simplify to get 16x^2-38x+12 = 0 Now factorise the LHS 16x^2 -32x -6x + 12 = 0 16x(x-2)-6(x-2) = 0 (16x-6)(x-2) = 0 x = 3/8 or x = 2. They are the …
