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 spectrum analyser plots amplitude against frequency, in other words it shows signals in the frequency domain. The spectrum analyser has the same trigger options as the oscillos
Q. What is Own-exchange routing? Distributed routing or own-exchange routing enables alternative routes to be chosen at intermediate nodes. Hence the strategy is capable of res
Q. Explain Resistance-capacitance coupling? It is the most commonly used coupling in discrete device amplifier as it is least expensive and has satisfactory frequency response.
