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).
Q. Can you show Binary Number Formats? We in general write binary numbers as a sequence of bits (bits is short for binary digits) and we have defined boundaries for these bits.
Q. Consider the circuit of Figure with V S = 94 V, V Z = 12 V, R = 820 , R L = 220 , R S = 0, and R Z = 25 . Assume the reverse saturation current of the zener diode to be
