FAQ

What is the definition of analog signal?

1. An analog signal is a representation of information that varies continuously over time.
2. It is a way of transmitting data that can take on an infinite number of values ​​within a given range.

What devices can generate analog signals?

1. Function generators.
2. DAC Modules (Digital-Analog Converter).

What are the steps to generate an analog signal with a function generator?

1. Connect the function generator to a power source.
2. Select the desired waveform, such as sine, square or triangular.
3. Adjust the frequency and amplitude of the signal.
4. Connect the output of the function generator to the circuit or equipment that will receive the analog signal.

How does a DAC module work to generate an analog signal?
