I've a full bridge rectifier and I put the following function into it:
So, at the output I get:
Where \$V_d\$ is the voltage over one diode.
Now, why do I measure (with a Fluke multimeter) a DC-voltage of \$1.4\$ volts and an AC-voltage of \$0.5\$ volts. Why do I measure an AC-voltage, is it not completely DC?
