2.
The falling ( negative ) edge of the pulse is used to start a monostable multivibrator in the slave device.
3.
The simplest SSI slave interface uses a retriggerable monostable multivibrator ( monoflop ) to freeze the current value of the sensor.
4.
When triggered by an input pulse, a monostable multivibrator will switch to its unstable position for a period of time, and then return to its stable state.
5.
In the monostable multivibrator, one resistive-capacitive network ( C 2-R 3 in Figure 1 ) is replaced by a resistive network ( just a resistor ).
6.
This was a monostable multivibrator, known as a One-Shot or Kipp Relay, that triggered the coarse time base, offsetting its starting point so it did not trigger immediately after the transmission, but a selected time after that.
