What is defined as the weakening of signal amplitude as the signal passes through a medium?

  1. Diffraction
  2. Reflection
  3. Attenuation
  4. Scattering

Answer(s): C

Explanation:

Attenuation: Describes the progressive loss of signal strength as it travels through a medium (like air, cables, walls). It's caused by factors like absorption, distance, and obstacles.
Other Phenomena:
Diffraction: Bending of waves around obstacles.
Reflection: Waves bouncing off surfaces.
**Scattering: ** Waves dispersing in multiple directions.

How is ASK modulation different from FSK modulation?

  1. ASK varies the amplitude of the signal while FSK shifts its frequency
  2. FSK is more sensitive to noise than ASK
  3. ASK does not work at high frequencies
  4. ASK can carry more data than FSK

Answer(s): A

Explanation:

Key Modulation Differences:
ASK (Amplitude Shift Keying): Digital data is represented by changes in the amplitude (strength) of a carrier wave.
FSK (Frequency Shift Keying): Digital data is represented by changes in the frequency of a carrier wave.

What does the number in the various Quadrature Amplitude Modulation levels, such as 16 in QAM- 16 and 64 in QAM-64, indicate? (Choose the single best answer.)

  1. The speed of data transfer, which is four times the number in the QAM level
  2. The channel width, which is stipulated in MHz
  3. The number of target points in the QAM constellation, which are equivalent to amplitude and phase combinations
  4. The number of spatial streams, which is 1/4 the number in the QAM level

Answer(s): C

Explanation:

QAM Constellations: QAM (Quadrature Amplitude Modulation) uses a constellation diagram where points represent unique combinations of amplitude and phase. Bits per Symbol: The number in QAM-XX indicates the number of points:
QAM-16: 16 points = 2^4 = 4 bits per symbol
QAM-64: 64 points = 2^6 = 6 bits per symbol
Higher Data Rates: More points in the constellation enable transmitting more bits per symbol, leading to higher data rates at the same bandwidth.

What modulation is used by LoRa?

  1. OFDMA
  2. CSS
  3. ASK
  4. OFDM

Answer(s): B

Explanation:

LoRa Modulation: LoRa (Long Range) is a proprietary wireless technology that utilizes Chirp Spread Spectrum (CSS) modulation.
CSS Characteristics:
Spread spectrum technique for resilience against interference. Chirps (frequency sweeps) enable operation below the noise floor for long range.

What primary component is required to implement a wireless transceiver in a device?

  1. GPIO pins
  2. SRAM
  3. Flash memory
  4. Radio

Answer(s): D

Explanation:

Wireless Transceiver: A transceiver is a combination of a transmitter and receiver used for wireless communication.
Radio: The radio is the primary component responsible for:
Modulation: Encoding data onto a carrier wave.
Demodulation: Extracting data from a received signal.
Transmission/Reception: Handling the actual sending and receiving of modulated signals over the air.
