What is amplitude spectrum?
The amplitude spectrum is a plot that shows the distribution of amplitude values of a signal across various frequencies. It provides information about the strength or magnitude of each frequency component present in the signal. The amplitude spectrum is commonly used in signal processing and audio analysis to characterize the frequency content of a signal.
What is the purpose of spectrum analyzer?
A spectrum analyzer is used to analyze and visualize the frequency content of a signal. It helps in identifying the presence of specific frequencies, measuring signal strength, and detecting interference or noise in the signal. Spectrum analyzers are commonly used in various industries such as telecommunications, audio engineering, and electronics for troubleshooting and signal analysis.
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.
Why you need spectrum of periodic signal?
The spectrum of a periodic signal provides information about the frequency content of the signal, which is crucial for analyzing and understanding its behavior. By decomposing the signal into its constituent frequencies, one can identify specific frequency components present, their magnitudes, and their phase relationships, aiding in tasks like filtering, modulation, and signal processing. It allows for a comprehensive understanding of the signal's characteristics in the frequency domain.
What is an audio spectrum analyzer?
Audio frequency spectrum is measured in Hertz's (Hz) and tells the range of audible audio. The human hearing range is usually 20-20000Hz, but especially the audibility of the top end of the spectrum declines with age. Most software analyzers measure between 0 Hz and 16000-24000kHz
What is relationship between signal spectrum and bandwidth?
Signal Bandwidth is the Bandwidth of particular frequency at which signal is transmitted and Bandwidth of spectrum which can able two show number of signal between Intrest of frequency.

What is the label on the y-axis of a mass spectrum?
"signal intensity" is the y- axis of a mass spectrum.

What defines the bandwith of a composite signal?
The width of the frequency spectrum
What is essential bandwidth of FM signal?
"Essential bandwidth" is the portion of the signal spectrum that encompasses most of the energy of the original signal in the frequency domain.
Why is the frequency spectrum of a discrete signal repetitions of the spectrum of the analog signal?
The analog signal is converted to discrete signal. Even after the conversion, the frequency of the actual signal still remains the same. If the frequency of the discrete signal is different from the analog signal, the reconstructed signal would be different again. This is not what we expect. So base spectrum for similar signals have same frequencies, whether they are discrete or analog. Why do the repetitions occur? The original analog signal is multiplied with a dirac pattern. The base frequency is then shifted to the places, where diracs are available. So long the diracs keep repeating, the base frequency do repeats. Hope you are convinced with my answer

What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
Is sawtooth signal analog?
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
