This image illustrates the output signal of an RC low-pass filter (10 MHz cutoff frequency).The input square wave signal of 6 MHz (blue) and the output signal (black) are shown.
- Filters are linear time-invariant (LTI) systems. LTI systems are both linear and time-invariant.
- Linearity means that the output of a linear combination of inputs is proportional to the combination of individual responses to those inputs.
- Time-invariance means that the output is independent of when an input was applied.
- These properties make LTI systems easy to understand and describe using transfer functions and impulse responses.
- The formula shows the convolution of the input signal and impulse response resulting in the output signal.
- An important application of LTI systems are filters in electrical circuits.
