WebThe bandwidth of one bin depends on the RBW: So with a with a sample rate of 48 kHz and an FFT length of 1024, we get an RBW of 48000 / 1024 = 46.875 Hz. With a screen width of 1024 pixels each pixel represents one bin. But HDSDR normalizes the FFT power by dividing with RBW and then converting to a level in dB. WebGain Reduction (dB) – The gain reduction value controls the amount of gain, in dB, that the maximum tuner gain will be reduced by. For example a gain reduction of 50 represents 50dB below maximum receiver gain. This value is tied to the gain control slider. Hotkeys + and – can also be used for this control.
