    Adc Fft Output
Click For Summary
To calculate the FFT from ADC output, the digital signal must be sampled correctly, typically resulting in a real-valued output. Since the imaginary part is zero for real signals, the FFT can still be computed using algorithms designed for real inputs. The process involves applying the FFT algorithm directly to the real-valued samples obtained from the ADC. Understanding the sampling rate and ensuring adequate resolution are crucial for accurate FFT results. Proper implementation will yield frequency domain information from the time-domain signal captured by the ADC.

Hi All,
Its my first post here. I want to know how the digital output which comes out of an ADC can be used to calculate FFT. Because FFT algorithms usually needs real and imaginary parts of a sampled signal?

Thanks.

The imaginary part is zero.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
