Explain Magnetostriction.
Magnetostriction: If ferromagnetic materials are magnetized a small change of dimensions of the material obtains place. There is a small extension along with equivalent reduction of cross-section of the crystals of that the material is made. When this rapidly alternating magnetic fields so there is a rapid and continuous extension and contraction of the material. It is termed as magnetostriction. This magnetostriction is the main cause of hum in transformers and chokes.
Given that a BJT has β = 60, an operating point defined by I CQ = 2.5 mA, and an Early voltage V A = 50 V. Find the small-signal equivalent circuit parameters g m , r o , and rπ.
Circuit with capacitive load Capacitors which obey the relationship of equation are linear capacitors, since the potential difference among the conductive surfaces is linearly
Q. Explain Charge-to-Charge Amplifier A circuit is shown in Figure in which there is a capacitor C1 in the - input line and a capacitor Cf in the feedback loop. KCL at node X g
Port Address The port address is of 8 bit it is range from 00H to FFH. It means there may be total i 256 input ports and 256 output port which can be accessed by 8085
Q. Digital demodulator processes? The functions of the receiver in Figure are the inverse of those in the transmitter. At the receiving end of a digital communication system, t
