If we decide to stay away from $\text{IEEE 754}$ format by making our Exponent field $10$ bits wide and our Mantissa field $21$ bits wide, then which of the following statement is $\text{TRUE}$?

  1. It will provide less precision as there will be fewer Mantissa bits
  2. It will provide more precision as there will be fewer Mantissa bits
  3. None of the above
  4. It will not change the precision

Precision depends on the bits in Mantisa. More the bits on Mantisa, more is the precision and vice-versa.

Range of numbers depends on Exponent. More the bits on expoenet, more is the range and vice-versa.

If $703_{x}$ (in base-$x$ number system) equals $504_{y}$ (in base-$y$ number system), then possible values of $x, y$ are: $17, 18$ None of these $8, 11$ $12, 13$

The decimal value $0.625$ equals the binary $0.111$ equals no finite binary string equals the binary $0.101$ equals the binary $0.10011$

Which of the following circuits are equivalent (i.e., they produce the same output for all inputs)? $\text{F} = ab + bc + ca$ $\text{G} = (a+b)(b+c)(c+a)$ $\text{H} = \text{NAND(NAND(a,b), NAND(b,c),NAND(c,a))} $ $\text{F}$ and $\text{H}$ $\text{F}$ and $\text{G}$ $\text{F, G}$ and $\text{H}$ $\text{G}$ and $\text{H}$

Let $\text{MXI}$ be an inverting $2:1$ multiplexer whose output is $a’,$ when $s=0$ and output is $b’$ when $s=1.$ That is, $\text{MXI}(s,a,b) = s’a’ + sb’.$ What function is the following circuit equivalent to? Exclusive $\text{OR}$ Exclusive $\text{NOR}$ Inclusive $\text{OR}$ Half adder sum
