Lingïísticos signs (units of language) divide their time in various, components that are studied in various fields of linguistics. These components are linked together, combine or unite to give rise to larger units. Thus we see that the various phonemes (sound units) meet to give rise to combinations of sounds that allow recognition of different concepts, training of all signs that constitute language.

In the field of morphology (the study of word formation), these smaller units are called monemes.

The combination of monemes will result in the formation of different words.

So that the linguistic sign (the word) comes from a double joint, a joint or combined sound (phoneme) meaningless and another that provides meaning (monemes).

Characteristics of Wireless Communication

• Information is sent and received using areal, infrared light, or ultrasound signals.
• The waves are propagated through space at the speed of light.

Characteristics of a Wave

1. Amplitude: The maximum value that a wave can reach, which depends on the wave's energy. The value diminishes with distance and is measured in meters.
2. Frequency: The number of times the wave oscillates per second, measured in Hz.
3. Period: The time it takes for the wave to complete a cycle, measured in seconds.
4. Wavelength: The distance it takes for a wave to complete a cycle, measured as the distance between two crests.

Electromagnetic Spectrum

The electromagnetic spectrum encompasses all electromagnetic waves from low to high frequency.

Portfolio Theory and Expected Returns

1. Expected return of the portfolio: μ_P = w₁μ₁ + w₂μ₂.

Standard deviation of the portfolio return: σ_p = √(w₁²σ₁² + w₂²σ₂² + 2ρw₁w₂σ₁σ₂).

• Suppose two investments R₁ and R₂ with expected returns μ₁ and μ₂.
• w₁ is the proportion of money in the first investment.
• σ₁ and σ₂ are the respective standard deviations.
• ρ is the coefficient of correlation between the two investments.

Market Portfolio and Systematic Risk

2. Relationship between any investment and the market portfolio: R = a + βR_M + ε.

• R = return from investment.
• R_M = return from market portfolio.
• a and β are constants.
• ε is a random variable representing the regression error.
• βR_M: Systematic risk.
• ε: Non-systematic risk.
