DH_HzToVoltage

Converts a frequency in Hz to the SE volt/octave scale with 440 Hz = 5 volts, using the formula:

V = ( log( f ) - log( 440 ) ) / log( 2 ) + 5

Inputs: 
Hz in - the frequency to be converted

Outputs:
Volts out - control voltage corresponding to the input frequency.

Version History: 
1.3 - August 29, 2005 - Calculations now done on sample-accurate basis instead of once per block. Updated to SDK2. Renamed DH_HzToVoltage

1.2.1 - July 10, 2005 - Maintenance release. Recompiled with SDK v1.1

1.2 - March 4, 2003 - Maintenance release. Updated with latest SDK, added sleep mode, and added default parameter range for Hz ( 0 to 4400 )

1.1 - January 28, 2003 - Fixed bug that sometimes resulted in invalid output as input approached 0.
