What electronics are involved to build a device like a guitar tuner where you press a button to get a specific tone What electronics are involved to build a device like a guitar tuner where you press a button to get a specific tone? Why BJT is called current control device? Latest Answer : Because the input current of the transistor controls the output current, for example in CE configuration base current Ib controls the output current Ic. ... Why FET is known as voltage control device? Latest Answer : Since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as voltage controlled device.For example: In a MOSFET, the current from drain to source depends upon the width of the depletion ...
