Yes, there is a difference in the output of active high decoders and active low decoders.
An active high decoder is a digital circuit that decodes a binary input to select one of several output lines, and its outputs are active when the input is high. The output is a logic level '1' when the input matches the corresponding code, and the output is '0' when the input is not the corresponding code.
On the other hand, an active low decoder is a digital circuit that decodes a binary input to select one of several output lines, and its outputs are active when the input is low. The output is a logic level '0' when the input matches the corresponding code, and the output is '1' when the input is not the corresponding code.
Therefore, the output of an active high decoder is the complement of the output of an active low decoder for the same input code. For example, if an active high decoder has an input code of "101," then its output will be '1' on the second output line and '0' on the other output lines. In contrast, an active low decoder with the same input code will have '0' on the second output line and '1' on the other output lines.
