Model a dual-tone multifrequency (DTMF) generator and receiver. The model includes a bandpass filter bank receiver, a spectrum analyzer block showing a spectrum and spectrogram plot of
Compare three different delta-modulation (DM) waveform quantization, or coding, techniques.
Implement two common methods of envelope detection. One method uses squaring and lowpass filtering. The other uses the Hilbert transform. This example illustrates MATLAB® and Simulink®
Use a Kalman filter to estimate an aircraft's position and velocity from noisy radar measurements.
Use the UDP Send and UDP Receive System objects to transmit audio data over a network.
SAR  is a technique for computing high-resolution radar returns that exceed the traditional resolution limits imposed by the physical size, or aperture, of an antenna. SAR exploits
Use the digital up converter (DUC) and digital down converter (DDC) System objects to design a Family Radio Service (FRS) transmitter and receiver. These objects provide tools to design
Illustrates using the UDP Send and UDP Receive blocks to transmit audio data over a network.
Use the digital down converter (DDC) System object to emulate the TI Graychip 4016 digital down converter in a simple manner. We base the example on a comparison with the GSM Digital Down
An implementation of a digital receiver that synchronizes to the time code information broadcast by radio station WWV and decodes it to display time information. The example uses the
Design filters given customized magnitude and phase specifications. Custom magnitude and phase design specifications are used for the equalization of magnitude and phase distortions
Use complex multirate filters in the implementation of Digital Down-Converters (DDC). The DDC is a key component of digital radios. It performs the frequency translation necessary to
Implements the Internet Low Bitrate Codec (iLBC) and illustrates its use. iLBC is designed for encoding and decoding speech for transmission via VoIP (Voice Over Internet Protocol).
Reconstruct three independent combined signals transmitted over a single communications link using a Wavelet Transmultiplexer (WTM). The example illustrates the perfect
Use a MIDI control surface as a physical user interface to a Simulink model, allowing you to use knobs, sliders and buttons to interact with that model. It can be used in Simulink as well as with
Use the DSP System Toolbox™ and Fixed-Point Designer™ to design a three-stage, multirate, fixed-point filter that implements the filter chain of a Digital Down-Converter (DDC) designed
