A synchronous circuit is a circuit in which the parts are synchronized by means of a clock subcircuit. There are many kinds of circuit An electric circuit interconnects electrical elements. ... A clock (from the Latin cloca, bell) is an instrument for measuring time. ...
In a synchronous circuit, every change in the logical levels of its components is simultaneous. The commutations follow the level change of a special synchro signal, called "clock". No matter how long may be a logical chain, there are no delays between the clock and the other parts' logical transitions, so the behaviour of the whole circuit -in any point- can be foreseen exactly at any speed.
The synchronous detection track circuit system, as defined in claim 4, wherein said impedance bond is connected to a demodulator which decodes the coded carrier signals to provide code signals to a synchronous rectifier which also receives a reference signal from said source of code signals.
The synchronous detection track circuit system, as defined in claim 1, wherein each of said transmitters includes a source of carrier frequency signals and a source of code signals connected to a modulator which supplies coded carrier signals to an amplifier which is coupled to the track rails by an impedance bond.
The synchronous detection track circuit system, as defined in claim 12, wherein a remote impedance bond is connected across the track rails for defining a block section which is powered by a transmitter having said first carrier frequency signal which is modulated by code signals having a phase angle which is 180.degree.
