Q. Three waveforms seen on an oscilloscope are shown in Figure. If the horizontal scale is set to 50 ms per division (500 ms for the entire screen width), and the vertical scale is set to 5 mV per division (±25 mV for the entire screen height with zero voltage at the center), determine: (i) the maximum value of the voltage, and (ii) the frequency for each of the wave forms.
Q. Define Number Systems? A number system, in general, is an ordered set of symbols (digits) with relationships defined for addition, subtraction, multiplication, and division.
Q. Implement the following Boolean functions by employing 8-to-1multiplexers. (a) F 1 (A,B,C) = Σ m i (0, 2, 4, 6) (b) F 2 (A,B,C) = Σ m i (1, 3, 7)
Q. Consider a BJT switch connected to the next stage, as shown in Figure, in which iout is likely to be negative when v out is high. Assume V CC = 5 V, R C = 1k, and the high r
3) A sine wave oscillator, in effect, converts
Design : Rather than 100 two-motion selectors as in the case of Design 3, let's consider only 24 two-motion selectors. In the case 24 simultaneous calls can be put through the swi
Armature Reaction in DC Generator: Armature reaction is the effect of magnetic flux set up by armature current upon the distribution of flux under the main poles.
The upper end of a hanging chain is fixed whereas the lower end is attached to a mass M. The (massless) links of the chain are ellipses with major axes and minor axes l+a and l-
ABCD propagation of an optical ray through a system can be explained by a simple 2_2 matrix. In ray optics, the characteristic of a system is given by the corresponding ray matrix
Q. Mention The Three Transistor Configurations? The three transistor configurations are 1)Common emitter configuration 2)Common base configuration 3)Common collector c
Q. Describe the operation of 8279. And also explain following terms: (i) N key Roll over. (ii) Key board debounce. (iii) FIFO RAM. Ans: 8279 is a programmabl
