Therefore, by adding an extra resistor and steering diode the tone duration can be set to different values.
The circuit also provides an excellent bridging interface across a properly terminated telephone line. Distorted Sine output from Transformer 8. When enabled by TOE, provide the code corresponding to the last valid tone-pair received see Table 1. Get best deals for coconut. This pin is pulled up internally.
Since inception incompany has expanded to become a national provider of hands-on science and technology education in India. The optional circuit shown within dotted line is used for oc time adjustment. kt8870
