Digital

This circuit can for example be incorporated into a diet to pressure warning. The meter can measure voltages from -99 mV to 999 mV. The circuit uses two ICs, the CA 3161 and CA 3162. IC1 converts the analog signal into a digital signal. IC1 is also the multiplexed signal to T1-T3 can be controlled. [...]

With this counter you can count laps for example (in conjunction with the Simple light trap ). The circuit uses two TTL ICs 74LSxx the series. The left IC is a decimaalteller. The input pulses 14 are counted and converted to the corresponding BCD code. This code is passed to the second IC, which is [...]

This is an SCR control circuit with digital logic. The behavior of the circuit. The input A to control current for SCR turn ON.The input B will stop the current SCR (OFF). Set the two input signals to a logic “1″ to control, and it asked them to different times. The control SCR to conductors. [...]
