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 advantage of the analog storage oscilloscope is that it has higher bandwidth and writing speed than a digital oscilloscope, being capable of operating speeds of about 15 GHz. T
Athree-phase,wye-connected, 220-V, 10-hp, 60- Hz, six-pole inductionmotor (using Figure 13.2.6 for notation) has the following parameters in ohms per phase referred to the stator:
design a excess3 to bcd code converter using only nand gates
A signal comprises a bandwidth of 1kHz centred around 1kHz. A sine wave along with a frequency of 1250Hz is added to the signal. The bandwidth of the new signal is: 2250Hz
