What are the disadvantages of amplitude modulation?
The major disadvantages of amplitude modulation is that it is easily affected by atmospheric noise, other electrical signals and interference from electrical motors and generators. Practically, various types of atmospheric and other electrical disturbances are also reproduced in the amplitude modulation receivers. Hence, AM receiver can not distinguish between amplitude variations that represent the noise and those that contain the desired signal. Therefore, the reception is generally noisy.

How LVDT works? Basic concept of linear variable differential transformer
LVDT (Linear Variable Differential Transformer) is a passive transducer. It measures force in terms of displacement of ferromagnetic core of a transformer. It is based on the principle of magnetic induction. It consists of a primary winding and two secondary windings, which are placed on both sides of the core. The two secondaries (Sec1 & Sec2) have equal number of turns but they are connected in series opposition. Due to this connection, the e.m.f. induced in one coil opposes the e.m.f. induced in second coil and thus we get the difference of voltages at the output of LVDT.
