Signal-to-noise ratio demonstrator
How does music or speech sound in different signal qualities? Recognize that it's the signal-to-noise ratio (SNR) that matters. Observe the visual and auditive impact of added noise.
Analyze audio signals
Analyze audio signals in the time and frequency domain. Play any music wave file, microphone line-in or signal generator waveform. This audio software visualizes the signal in an oscilloscope and in a spectrum analyzer.
LTI system - RC low-pass filter
Measure amplitude and phase of the output sine wave signal using an oscilloscope. Compare the results with the transfer function representing the linear time-invariant (LTI) system.
In this scenario, a pulse is sent and shall be detected at the receiver. It might represent a symbol for digital transmission or a radar pulse. The received pulse might be almost hidden in noise...
