In the previous article we saw that a pulse-width-modulated signal can be “smoothed” into a fairly stable voltage ranging from ground to logic high (e.g., 3.3 V); the smoothing is accomplished by a simple low-pass filter. Thus, we can achieve digital-to-analog conversion by using firmware or hardware to vary … See more Let’s look at two-pole filter results for the same two cutoff frequencies. The following circuit is a critically damped RLC filter with fc ≈ 50 kHz (I used this online filter calculator toolto determine the component values): … See more Let’s see what kind of DAC quality we can get with a basic RC filter. We’ll start with a cutoff frequency (denoted by fc) in the middle of the DC-to-carrier band: fc=50kHz=12πRC;chooseC=10nF⇒R≈318Ωfc=50kHz=12πRC;chooseC=10nF⇒R≈318Ω Not so great . . . … See more We need not be discouraged by trade-off #2, because there is a straightforward way to get more performance out of an RC filter: just increase the … See more WebWow thanks guys!
