Explanation:
Transfer function is defined as the ratio of output to input in the Laplace domain. In the case of a tachometer, the input is the rotor displacement (a(t)) and the output is the output voltage (e(t)). The tachometer constant (K) is a parameter that relates the input and output.
The transfer function of a tachometer can be derived using the following steps:
1. Write the equation that relates the input and output:
e(t) = K * a(t)
2. Take the Laplace transform of both sides:
E(s) = K * A(s)
where E(s) and A(s) are the Laplace transforms of e(t) and a(t), respectively.
3. Divide both sides by A(s) to get the transfer function:
H(s) = E(s)/A(s) = K
Therefore, the transfer function is a constant value, which is equal to the tachometer constant (K).
Option C is the correct answer, which states that the transfer function is Ks/d. This is incorrect because the transfer function is a constant value (K) and does not have any s or d terms.
