Select the type of signal:
Type the signal of interest x(t). For a better visualization, it is recommended to maintain a domain of approx. 100 between the maximum and minimum points.
The signal must be expressed using singularity functions (i.e., u(t) [unit step], rect(t/T) [rectangular function], r(t) [ramp function], delta(t) [dirac delta function]), tri(t) [triangular function] and sgn(t) [signum function] as well as exponential and trigonometric functions:
Type the signal of interest x(t). For a better visualization, it is recommended to maintain a range of approx. 100 between the maximum and minimum points.
The signal must be expressed using singularity functions (i.e., u(t) [unit step], rect(t/T) [rectangular function], r(t) [ramp function], delta(t) [dirac delta function]) and trigonometric functions:
To avoid errors, please note the following:
- The tool is designed for functions, especially those commonly used in a typical Signals and Systems Course. Thus, single real numbers will not be plotted.
- * must be used for multiplication.
- ^ must be used for power except the exponential function.
- An exponential function should be expressed as e(***). Example, e^-t = e(-t).

Type y(t) as a function of x(t): (Please follow A*x(a*t+b)+B)
Type the impulse response h(t) of LTI system:
Type y[n] as a function of x[n]: (Please follow A*x[a*n+b]+B)
Type the impulse response h[n] of LTI system:
y(t) = x(t)*h(t) is shown below:
y[n] = x[n]*h[n] is shown below:
