Explain ferrites and its uses in high frequency devices.
A group of magnetic alloys show the property of magnetisation that change, with percentage of various constituent atoms in the alloy. Illustration XOFe2O3 with X= Mn, Copper, Nickel, Zink, Mg, Cd or Fe++. The alloys are termed as ferrites. Manganese ferrite is a mixture of iron oxide and manganese oxide. Ferrites are extensively used in computers and in microwave equipment. Ferrites are advantageous at high frequencies due to low eddy current losses. The ferrites crystallise in what is termed as the spinel lattice. The resistivity of ferrites is higher than the ferromagnetic metals. Ferrites are brittle and hard materials that cannot be shaped trough ordinary machining processes. Ferrites are also used in recording tapes, transducer applications and compact aerials for focussing magnets of TV picture tubes and for radio sets.
#The requirement is as follows- There is a signal which is in the range of 0 to 5Hz. This signal frequency composition is to determined. The resolution of the determination is 1Hz.
If the message has a spectrum where K and Wf are positive constants, sketch the spectrum of a standard AM signal that uses the message. Comment on the physical signi?cance
Q What do you mean by Direct coupling? In this method the a.c. output signal is fed directly to the next stage. No reactance is included in this coupling network. Special d.c.
What is 16-bit ISA? Compare it with 8-bit ISA bus. The only difference among the 8 and 16-bit ISA bus is that other connector is attached behind the 8-bit connector. This 16-bi
Q. When the J and K inputs of a JKFF are tied to logic 1, this device is known as a divide-by-2 counter. Complete the timing diagram shown in Figure for this counter.
Explain SEGMENT assembler directive with example. SEGMENT: This directive described to the assembler the start of a segment along with name segment-name. The seg
Q. Draw the circuit of a 7805 voltage regulator? Explain the functions of the capacitors used at its input and output sides. Functions of capacitors used at input and outp
Q. Show the procedure of Octal to Decimal Conversion? To convert from Octal to Decimal, multiply the value in every position by its Octal weight and add each value. Using the v
stack Pointer (SP) It is also a 16 bit register and a memory pointer similar to program counter. It holds the memory address of the top of the stack. Stack is a part of
