A MOSFET has its source grounded and the body connected to -1.5V. It is known that the flabband voltage VFB is -2V and the threshold voltage VT is 0.6V. The increase in VT relative to the case with 0 body bias is 0.8V (i.e. AVT = 0.8V). Now, 1V is applied to the body and 2.5V is applied to the source. %3D What is the new value of the flatband voltage (VFB)? V What is the value of the new threshold voltage (VT)? V

Amplitude modulation

A radio signal can carry information in the form of sound or image for broadcasting or communication. For it to be sent to a greater distance, the signal must be changed or modulated in some way. One of the easiest way is to change the amplitude of the signal with variations of the video or the audio signal. This is called Amplitude Modulaton. In this modulation information of message is carried in amplitude of carrier signal.
