Q. Explain about Differentiator?
Shown in Figure is a differentiator which is obtained by replacing R1 in the inverting amplifier of Figure by a capacitor C. Assuming ideal op-amp characteristics, one has i = iC and vo = - Ri = - RiC. But since iC (t) = Cdvin (t) /dt ,we get
vo (t) = - RC dvin (t) / dt
which corresponds to a differentiator with a gain of -RC. In practice, however, differentiators are normally avoided because of high-frequency noise (which is accentuated due to a transfer function that increases with frequency) and stability problems (which make them oscillate).
The corners of wedge-shaped block are A(0,0,2), B(0,0,3), C(0,2,3), D(0,2,2), E(-1,2,2) and F(-1,2,3) and the reflection plane goes the Y-axis at 450 between (-X) & (Z) axis. Calcu
Q. Applications of operational amplifiers? An op amp along with a few external components (resistors and capacitors) is capable of performing many different operations-hence th
I want to know how can i make transformerlass power supply 220v to 48v (8A) and 220v to 24v (8A)
Classify plastic materials into two categories describe their important properties and give two examples of each. Plastic materials can be categorized in thermoplastic and ther
The vectors we will use we be refered to right-handed Cartesian axes. Right handed means that the x,y,z axes are oriented in a particular way (which you must know). See diagrams
Q. Explain about Address Structure? Address Structure: ISDN address structure is illustrated in figure. ISDN number part has a maximum of 15 digits and ISDN sub address part
