geez - garble things much?

Answer 2

It's 7.

To find the value of K, we need to look at the steady-state output equation:

V_o = K + A_o*cos(3000t + θ)

From the given information, we know that the input is V_in = 7 + 10*cos(3000t).

The steady-state output occurs when the system has settled and stabilized to its final response without any transient effects. In this state, the system responds only to the sinusoidal part of the input.

So, in the steady-state, the cosine term cos(3000t) in the input will produce a cosine term in the output with the same frequency of 3000t. The amplitude of this cosine term in the output will be denoted as A_o.

Since the input does not have any DC offset (constant term), the steady-state response should also not have any DC offset. This means K should be zero.

Therefore, the value of K in this case is 0.
