Dynamic Equalizer (16 QAM Modulation) This diagram illustrates the use of baseband equalization to compensate for channel distortions on a 16 QAM link. A modulated signal is distorted via the use of a bandlimiting Chebyshev filter with about 3 dB of ripple across the band. The effects of the filter on the modulated signal are evident by looking at the Eye Plot and Phase Scatter Plot.
BSPK Receiver Tracking Example Pseudo-random binary data is generated, BPSK modulated, corrupted with noise, and then demodulated using a Phase Locked Loop
Fast Fourier Transforms The FFT block performs a one-time FFT or IFFT and is controlled by an external trigger. The output of the FFT block can be treated as a time domain signal within the simulation and manipulated as such
Nonlinear Amplifier This example illustrates the various intermodulation products formed when two tones are passed through an amplifier close to its compression point
Frequency Response of FIR Filter This simulation illustrates the use of the FFT block to obtain the frequency respnse of an FIR filter from its impulse response
V.32 Trellis Coding Example This example illustrates an implementation o fthe V.32 Trellis Coding scheme. The information bit stream is encoded, distorted and then recovered.
"Due to its power, flexibility, ease-of-use, and low cost, VisSim has been Carrier's choice for system modeling, simulation, data acquisition, and rapid prototyping for over eight years." Mr. Richard Kolk - Manager Simulation & Control Technology
"For my current project, VisSim has allowed me to collapse my firmware development time from months down to about a week. It is almost impossible to overstate the importance of VisSim to my development time-table." -Greg Gottschalk Electrical Engineer
