signals of which are received by the receivers of the sensor section.
The receiver section consists of two identical light detecting resistors. When the signal from the transmitters are received ; a low dc level (logic low) is obtained at the output. But once the signal is cut ,the output obtained is at logic high.
The +5V dc level occasionally drops to zero, even when the signal strength is quite low, due to very high sensitivity of the receiver. This may lead to the false triggering of the circuit, which must..................[:=> Show Contents <=:]

it is transferred to full swing logic signal.
When input signals are recognized to be effec¬tive, DV becomes high, and the correct tone code (DTMF) digit is transferred.
Steering control circuit
The steering control circuit is used for measur¬ing the effective signal duration and for protect¬ing against drop out of valid signals. It employs the analog delay by external RC time-constant controlled by EST.
The timing is shown in Figure 3. The EST pin is normally low and draws the RT/GT pin to keep low through discharge of external RC. When a valid tone input is detect..................[:=> Show Contents <=:]
