Sawtooth waves and real-world signals contain all integer harmonics. A curiosity of the convergence of the Fourier series representation of the square wave is the Gibbs phenomenon.
A laboratory type square wave and pulse generator is shown in Fig 6.
Generate square wave pulses at regular intervals - Simulink
The instrument can be operated as a freerunning genenrator or, it can be synchronized with external signals. The basic generating loop consists of the current sources, the ramp capacitor, the Schmitt trigger and the current switching circuit as shown in the fig 6.
When the positive slope of the ramp voltage reaches the upper limit set by the internal circuit components, the Schmitt trigger changes state. The trigger circuit output becomes negative and reverses the condition of the current switch.

In order to be able to provide the right kinds of pulses a considerable degree of adjustment is required for the pulses in terms of length, delay, repetition rate and the like.
Many of the functions of a pulse pulse and square wave generator are similar to those of a function generator or arbitrary waveform generator.
As pulse and square wave generator result, many function or arbitrary waveform generators include function generator capabilities, making them multi-purpose test instruments. Pulse generator basics Pulse generators are used to provide pulses for use in a variety of electronic applications.
Typically pulse generators will provide a number of functions and capabilities: For example, the first element of a vector amplitude parameter determines the amplitude of the first element of a vector output pulse.
All the waveform parameters must have the same dimensions after scalar expansion. The data type of the output is the same as the data type of the Amplitude parameter. Use the Pulse type parameter to specify whether the block's output is time-based or sample- based.

If you select sample-based, the block computes its outputs at fixed intervals that you specify. Pulse and square wave generator you select time-based, Simulink software computes the block's outputs only at times when the output actually changes. This choice can result in fewer computations for computing the block's output over the simulation time period.
The sample time color of such blocks is brown see View Sample Time Information for more information. Simulink cannot use a fixed-step solver to compute the output of a time-based pulse generator.
