Moving average filter using Blockram

Hello, I implemented moving average filter using block ram. I have to filter the output of ADC. Sampling frequency of 8 bit ADC is 1.5Mhz. The ENOB for input...
Guaranteed stable sliding Goertzel implementation

Is it possible that a Chamberlin state variable implementation of the Sliding Goertzel (SG) resonator provides a stable implementation without introducing a dampening...
damping filter - finite stationary error

Hi,I need to make a damping filter that will produce for the given input signal desired output. In the desired output there is always some stationary error that...
FFmpeg Downsampling audio changes the spectral content

Hi,I am new to the forum. Please pardon if I am not following forum rules. I am downsampling an audio using ffmpeg from 32KHz to 8Khz. The log frequency spectrogram...
Detecting the center frequency of a all-pass filtered sound

Hi,would it be possible to detect the center frequency at which an audio signal has been all-pass filtered from a recording of it? I assume that if you know the...
with respect to puncturing associated with channel coding, I have a question.So, when a code word is punctured at the transmitted how does the receiver know the...
Extract pitch of irregular signal ?

I have tried both autocorrelation and a simple FFT power spectrum, but I cannot see how I can extract the tone of this audio signal:

amplitude of passband frequencies in FIR bandpass filter

Hi allI wanted to generate broadband noise of specific amplitude for my simulations. To do so, i generated a random noise using MATLAB randn command and then design...
