Working and Circuit Diagram of Triangular Signal
Triangular Signal Generator
This circuit uses two operational amplifiers. The whole process requires two steps:
Square Wave Generation
Resistor R1 and capacitor C1 determine the frequency of the square wave. Resistor R2 and R3 forms a voltage divider setup which feedbacks a fixed fraction of the output to the non-inverting input of the IC. The voltage across capacitor C1 varies from 0 to Vcc using resistor R1. A fraction of this high voltage is fed back to the non- inverting pin by the resistor network R2, R3. When the voltage across the charging capacitor is increased to a point the voltage at the inverting pin is higher than the non-inverting pin, the output of the op amp swings to negative saturation (-Vcc). This cycle is repeated over time and the result is a square wave swinging between +Vcc and -Vcc at the output of the op-amp.
Integrator Output
An active integrator based on op-amp is used. Resistor R5 in conjunction with R4 sets the gain of the integrator and resistor R5 in conjunction with C2 sets the bandwidth. Square wave is given as input to inverting terminal of op-amp through resistor R4. The output of this circuit generates a cycle of triangular pulse.
Triangular Signal – Electrical Circuits
Triangular Signals are an important tool in the electronic industry. They are ubiquitous in modern electronics and are almost used in every daily appliance for Voltage, Current, and power amplifiers. In this article, we will study what a triangular signal, how does it look like. We will also represent the Triangular signal mathematically. Later we will discuss the advantages, disadvantages, and some applications of Triangular Electronic Signal. We will conclude the article by summing up what we have learned. The electronics industry especially the communication system uses these signals in various circuits and readers can read about these other signals as well.
