Function generator with CRO & Spectrum analyzer using GUI control. Five types of function can be generated & also the amplitude & frequency can be changed to visualize the time domain as well as frequency domain signal.

This exercise designs an automatic gain control (agc) system for speech companding. in matlab

The following Matlab project contains the source code and Matlab examples used for this exercise designs an automatic gain control (agc) system for speech companding. . This exercise designs an automatic gain control system for a speech waveform based on short-time estimates of the speech signal variance (or equivalently, the short-time standard deviation).

Optimization in cooperative spectrum sensing in cognitive radio network in matlab

The following Matlab project contains the source code and Matlab examples used for optimization in cooperative spectrum sensing in cognitive radio network. Cooperative spectrum sensing and adapting to the environment, a cognitive radio is able to fill spectrum holes and serve without causing harmful interference to the licensed user.

Amplitude modulation in matlab

The following Matlab project contains the source code and Matlab examples used for amplitude modulation. The codes in two files generate time and frequency domain representation of three basic types of amplitude modulation i>Double SideBand Amplitude Modulation (Full Carrier) (DSBAM) ii>Double SideBand Suppressed Carrier (DSBSC) iii>Single SideBand (SSB) The message signals used are combination of sinusoids of different frequency.
