Abstract
An apparatus and a method for counting input pulses during a specific time interval are provided. A clock edge recovery output signal is produced in response to an input gating signal and a clock signal containing the input pulses. The clock edge recovery output signal contains a respective full clock pulse for each of either the rising or falling edge of the input pulses of the clock signal that occurs while the input gating signal is in an enable state and when the input gating signal transitions from the enable state to the disable state. A counter circuit counts the pulses contained in the clock edge recovery output signal.
Claims18
An apparatus for counting input pulses during a specific time interval, comprising:
- an input gating circuit for performing input gating and producing a clock edge recovery output signal in response to a clock signal and an input gating signal, the clock signal containing the input pulses having edges of first and second directions, the second direction of the edges being an opposite to the first direction, the clock edge recovery output signal containing a respective full clock pulse for each of either of the first and second direction edges of the clock signal that occurs while the input gating signal is in an enable state and when the gating signal transitions from the enable state to a disable state;
- and
- a counter circuit for counting the pulses contained in the clock edge recovery output signal.
