Digital Equalizer on FPGA

Digital Equalizer on FPGA by Thales De Lima Beraldo

Audio digital signal processing is the intentional modification of the digital signals. Advanced digital signal processing systems require a high performance embedded computing. This process require a power efficiency once everything is happening in real time and audio applications cannot have a delay. With this processing method we can store, compress, transmit and enhance any digital signal. Knowing about this I could implement a Digital Equalizer with different bands of frequency. It consists of digital filters which will be followed by a gain controller to change the input signal depending what operation the user needs. This kind of equalizer can be applied to enhance the tones of musical instruments such as electric guitar, drums, flute, or either a human voice. Consequently, it could reduce some background noises which were interfering the music.
