Introduction of Function Generator Working with Block Diagram

Eltronicschool. - Maybe you will not foreign again with the function generator in electronic field now. This device will give you the output signal like sinous, square, and pulse for your project.

In this time we will show you the introduction of the function generator working with the block diagram look like in Figure 1 below.

Description

This is the function generator working for you. Accordingly Circuitstoday blog describe that a function generator is a signal source that has the capability of producing different types of waveforms as its output signal. The most common output waveforms are sine-waves, triangular waves, square waves, and sawtooth waves. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz.

The block diagram of a function generator is given in the figure. In this instrument, the frequency is controlled by varying the magnitude of the current that drives the integrator. This instrument provides different types of waveforms (such as sinusoidal, triangular and square waves) as its output signal with a frequency range of 0.01 Hz to 100 kHz.

The frequency controlled voltage regulates two current supply sources. Current supply source 1 supplies a constant current to the integrator whose output voltage rises linearly with time. An increase or decrease in the current increases or reduces the slope of the output voltage and thus controls the frequency.
