Abstract
Method and system for adjusting or controlling a noise floor of a filtered signal for low frequencies. A filtered digital signal, having M bits, is processed to form an one-bit XOR signal. This XOR signal is added to the filtered signal to produce a modified filtered signal. A selected number of LSB bits of the modified filtered signal is removed to form a dithered filtered signal with a noise floor that is reduced for low frequencies.
