Lecture 14 TimeFrequency Analysis Analyzing sounds as a sequence of frames Spectrogram Lossy Encoding MP3 encoding ELEC1200 1 TimeFrequency Analysis For many complex signals like speech music and other sounds short segments are well described by a sinusoidal representation with a few important frequency components but long segments are not. It abstracts key communications services and centralizes session management providing a vendor neutral infrastructure for delivery of next generation UC applications KEY FEATURES Centralized dial plan management Centralized session routing and forki Antti Meriläinen, Edward . Hæggström. Using high frequency acoustic waves for mm-/µm-scale imaging. Method is non-destructive. It “Sees” inside the sample. Ultrasound images differences of acoustic impedances. Examples of signals:. Voltage output of a RLC circuit, stock market, ECG, speech, sequences of bases in a gene, MRI or CT scan. Examples of systems:. RLC circuit, an algorithm for predicting future of stock market, an algorithm for detecting abnormal heart rhythms, speech understanding systems, edge detection algorithm for medical images.. 1.
