Properties of DTFT I01:24

Properties of DTFT I

837
In signal processing, Discrete-Time Fourier Transforms (DTFTs) play a critical role in analyzing discrete-time signals in the frequency domain. Various properties of the DTFTs such as linearity, time-shifting, frequency-shifting, time reversal, conjugation, and time scaling help understand and manipulate these signals for different applications.
The linearity property of DTFTs is fundamental. If two discrete-time signals are multiplied by constants a and b respectively, and then combined to...

Doppler Effect - II01:05

Doppler Effect - II

5.0K
The Doppler effect has several practical, real-world applications. For instance, meteorologists use Doppler radars to interpret weather events based on the Doppler effect. Typically, a transmitter emits radio waves at a specific frequency toward the sky from a weather station. The radio waves bounce off the clouds and precipitation and travel back to the weather station. The radio frequency of the waves reflected back to the station appears to decrease if the clouds or precipitation are moving...

Perceptual Constancy01:12

Perceptual Constancy

1.7K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Doppler Effect - I00:56

Doppler Effect - I

6.7K
The Doppler effect and Doppler shift were named after the Austrian physicist and mathematician Christian Johann Doppler in 1842, who conducted experiments with both moving sources and moving observers. Consider an observer standing on a street corner, observing an ambulance with a siren sound passing by at a constant speed. The observer experiences two characteristic changes in the sound of the siren. Initially, the sound increases in loudness as the ambulance approaches and decreases in...

Properties of DTFT II01:24

Properties of DTFT II

609
In the study of discrete-time signal processing, understanding the properties of the Discrete-Time Fourier Transform (DTFT) is crucial for analyzing and manipulating signals in the frequency domain. Several properties, including frequency differentiation, convolution, accumulation, and Parseval's relation, offer powerful tools for signal analysis.
The frequency differentiation property is illustrated by considering a DTFT pair and differentiating both sides with respect to ω.

Time and frequency -Domain Interpretation of Phase-lag Control01:21

Time and frequency -Domain Interpretation of Phase-lag Control

433
Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any...

Summary
This summary is machine-generated.

Subjective motion, even without actual stimulus movement, can cause time dilation. This suggests high-level visual processing influences our perception of time duration.

Area of Science:

  • Visual perception
  • Neuroscience
  • Cognitive psychology

Background:

  • Moving stimuli are perceived as longer in duration than stationary ones.
  • The role of subjective motion, independent of actual stimulus movement, in time perception is not well understood.

Purpose of the Study:

  • To investigate if subjective motion alone is sufficient to cause time dilation.
  • To dissociate actual stimulus motion from subjective motion perception.

Main Methods:

  • Utilized a motion illusion (jitter aftereffect) to create subjective motion from a static stimulus.
  • Measured subjective durations of static patterns with illusory jitter, actual oscillation, and no illusory jitter.

Main Results:

  • Both actual pattern oscillation and illusory subjective jitter induced significant time dilation.
  • The magnitude of time dilation was comparable for actual and subjective motion.

Conclusions:

  • Visual duration computation is influenced by high-level motion processing.
  • A stable visual world perception, despite retinal image motion, impacts subjective time perception.
