Solution
(1) Aliasing is an effect that causes different signals to become indistinguishable from each other during sampling. Aliasing is characterized by the altering of output compared to the original signal because resampling or interpolation resulted in a lower resolution in images, a slower frame rate in terms of video or a lower wave resolution in audio. Anti-aliasing filters can be used to correct this problem.
(2) The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signals. For analog-to-digital conversion (ADC) to result in a faithful reproduction of the signal, slices, called samples, of the analog waveform must be taken frequently
(3) Kirchhoff’s Current Law states that” the algebraic sum of all the currents at any node point or a junction of a circuit is zero”.
I = 0
Kirchhoff’s Voltage Law states that the algebraic sum of the voltages (or voltage drops) in any closed path of network that is transverse in a single direction is zero or in other words, in a closed circuit, the algebraic sum of all the EMFs + the algebraic sum of all the voltage drops (product of current (I) and resistance (R)) is zero.
E + V = 0
(4) Thesensitivity is usually defined as the flux density of a source that would produce the same signal power as the noise power, i.e. a signal/noise ratio of one.

(6) A confidence interval measures the probability that a population parameter will fall between two set values. The confidence interval can take any number of probabilities, with the most common being 95% or 99%
(7) The standard normal distribution is a special case of the normal distribution . It is the distribution that occurs when a normal random variable has a mean of zero and a standard deviation of one. The normal random variable of a standard normal distribution is called a standard score or a z score.
