1. The combination comprising:
- means for generating non-return-to-zero binary information signals;
means for modifying said signals to have rise times differing from fall times includingsignal output means,signal integrating means for producing an integrated signal to said signal output means,timing means responsive to said binary information signals for producing a timing signal having a duration less than each bit of said binary information signals, andgating means responsive to said timing signal for applying said binary information signals to said signal integrating means during the timing signal duration and otherwise to said signal output means; and
means for transmitting said signals from said signal output means to a receiving means.

Abstract
Circuit for modifying a transmitted Non-Return-to-Zero signal to insert a frequency component at the bit rate to permit linear processing at the receiver to extract timing signals.
