I don't know if this was discussed before, my question to you is resolution
at 4.0 Mhz.  If I were to display decimal frequency in the range of 0 to
120 Hz, the max resolution I can achieve is per bit 0.48 Hz.  It means if I
were to display a decimal point, each display advancement is 0.48Hz.  Is
there a way to improve this.
