Convolution of signals sampled on a logarithmic grid

1. What is the convolution of a signal with?
2. Which method can be used determine the convolution between two signals?

What is the convolution of a signal with?

Convolution is a mathematical way of combining two signals to form a third signal. It is the single most important technique in Digital Signal Processing. Using the strategy of impulse decomposition, systems are described by a signal called the impulse response.

Which method can be used determine the convolution between two signals?

Cross Correlation Function

Cross correlation is the measure of similarity between two different signals.
