What’s on the Impulse & Step Response poster
The rule, 3 worked examples, and the mistake everyone makes.
- The impulse response fully describes an LTI system, and every other response follows…
- y(t) = x(t) * h(t) · h(t) = d/dt of the step response
- RC low-pass h(t) = (1/RC) exp(−t/RC)
- Its step response = 1 − exp(−t/RC)
- Pure delay T = h(t) = δ(t − T)
- Common mistake: Reading the 10–90% rise time as the time constant → Rise time ≈ 2.2 τ…
Rise time and bandwidth are the same fact twice: for a first-order system their product is about 0.35.

- Who is the Impulse & Step Response poster for?
- Impulse & Step Response belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning signals & systems can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Impulse & Step Response poster?
- Measure the step response on a bench; differentiate it when you need the impulse response. A wall chart earns its place by being glanceable from where the work is happening, so Impulse & Step Response belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Impulse & Step Response?
- Convolution, Filter Responses and Bode Plots sit alongside Impulse & Step Response in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.ConvolutionFilter ResponsesBode Plots
- Is the Impulse & Step Response poster free to download and print?
- Yes. Impulse & Step Response downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Impulse & Step Response poster print at?
- Impulse & Step Response is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Impulse & Step Response loses nothing.Printing guide
