Doppler Effect - I00:56

Doppler Effect - I

6.8K
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...

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...

Properties of DTFT I

847
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...

Properties of Fourier Transform II

884
The Fourier Transform (FT) is an essential mathematical tool in signal processing, transforming a time-domain signal into its frequency-domain representation. This transformation elucidates the relationship between time and frequency domains through several properties, each revealing unique aspects of signal behavior.
The Frequency Shifting property of Fourier Transforms highlights that a shift in the frequency domain corresponds to a phase shift in the time domain. Mathematically, if x(t) has...

Speed of a Transverse Wave01:13

Speed of a Transverse Wave

4.2K
The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

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

Time and frequency -Domain Interpretation of Phase-lag Control

434
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...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Temporal Cognition

Background:

  • A prior study identified an asymmetry in subjective distance estimation between future and past.
  • This asymmetry was termed the temporal Doppler effect, characterized by a contraction of future distance judgments relative to past ones.

Purpose of the Study:

  • To replicate the temporal Doppler effect using real and imagined motion in both forward and backward directions.
  • To investigate the influence of different temporal perspectives on this effect.
  • To address potential subjective anchoring issues by comparing various motion and perspective conditions.

Main Methods:

  • Participants engaged in real and imagined self-motion (ego-moving) and external motion (time-moving) towards or away from a frontal target.
  • A control group was used for comparison.
  • Judgments of distance were collected under different temporal perspectives.

Main Results:

  • A Doppler-like distortion, where future distances were judged as contracted, was predominantly observed only when the distance between the participant and the target increased (moving away).
  • No significant effects of temporal perspective (e.g., past vs. future) were found on the observed distortions.
  • The effect was absent in conditions involving movement towards the target.

Conclusions:

  • The findings challenge current theories of temporal cognition by suggesting an absence of psychological movement into the future, supporting a
  • past-directed temporal Doppler effect.
  • The study indicates that temporal distortions are primarily linked to outward motion, not necessarily to future-oriented cognition.
  • This research opens new avenues for memory research and understanding human future construction.
