Frequency spread refers to the distribution or range of frequencies present in a signal or sound. It describes the spacing and coverage of individual frequencies within a given range. A wider frequency spread means there is a greater variety of frequencies present, while a narrow spread indicates a more limited range of frequencies.

What is meant by frequency Interleaving?
Frequency interleaving is a technique where consecutive symbols in a data stream are spread across different frequency subcarriers in a communication system. This helps combat frequency-selective fading in wireless channels by reducing the impact of frequency-specific signal impairments. By spreading the symbols across multiple frequencies, frequency interleaving helps improve robustness and reliability of the communication link.
What is spread spectrum radio?
Spread spectrum radio is a communication technique that spreads the signal over a wide frequency band. It enhances signal security, reduces interference, and improves signal quality by using a larger portion of the frequency spectrum. This technology is commonly used in wireless communication systems like Bluetooth and Wi-Fi.
What is the relationship between the keyword "frequency" and the variation in data points within a dataset?
The keyword "frequency" refers to how often a particular value appears in a dataset. The variation in data points within a dataset is related to how spread out or diverse the values are. Higher frequency of certain values can indicate less variation, while lower frequency can indicate more variation in the dataset.
What do high and low-frequency electromagnetic waves look like?
High-frequency electromagnetic waves have shorter wavelengths and higher energy, appearing as shorter, more tightly packed waves. Low-frequency electromagnetic waves have longer wavelengths and lower energy, appearing as longer, more spread out waves.
Can you describe what high and low frequency electromagnetic waves look like?
High frequency electromagnetic waves have shorter wavelengths and higher energy, appearing as shorter, more tightly packed waves. Low frequency electromagnetic waves have longer wavelengths and lower energy, appearing as longer, more spread out waves.

What is the signaling method used by Bluetooth?
FHSS(Frequency Hopping Spread Spectrum)
This shows how the data set as a whole is spread around the mean?
A frequency distribution plot.
What are the variables when light is spread through a glass block?
velocity of light, amplitude , frequency etc
What are the Four primary technologies in which wireless lans uses in transmitting and receiving data?
a. Direct sequence spread spectrum (DSSS). b. Frequency hopping spread spectrum (FHSS). c. Infrared d. Orthogonal frequency division multiplexing(OFDM)
How would you describe the spread for a dot plot?
The spread is the minimum value (not count) to the maximum value. The range is the maximum value minus the minimum value. Spread does not consider the frequency of the values, only the minimum and maximum.
Which graphic display shows the median and data spread about the median?
A frequency diagram or, for grouped data, an histogram.
What is Modulation index in Frequency modulation?
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
What is the frequency blue tooth runs on?
Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping.

What is the effect of varying frequency of the carrier signal on the AM wave?
spread spectrum , modulation or depending on the bandwidth poss FM (deviation)
