Musical instruments are a great way to explain the constructive interference example. They have sound waves that interfere with each other and give a result in the form of constructive or destructive. Mainly string instruments contribute mainly to constructive interference. Let’s take guitar as an example for this concept. smith epard

When the instruments are weak, the TS2SLS estimator, just like the classic (one-sample) 2SLS estimator, is no longer asymptotically normally distributed, inval-idating the conventional inference methods based on normal approximation. Nettetignored the issue of instrument relevance and has focused only on verifying instrument exogeneity.2 To rectify this imbalance, recent research has emphasized that an IV estimator will have poor finite-sample performance if the instruments have low relevance for the regressors.
