An excellent tone burst generator can be made using 556 Dual Timer. We can connect the first half as a one-shot and the second half as an oscillator. The oscillator turns on because the pulse established by the one-shot turns, allowing a burst to be generated. Here is the circuit diagram: [Source: Philips Semiconductors Application Note]

Only with a single chip active component (4069 IC), this circuit will convert sine to square waves without a power-source. To test some audio instruments, we can use this circuit. Device purpose: This circuit intended to pick up the a sine wave from an existing generator and then converts that wave into good square waves. This circuit doesn’t need power-source, […]

To generate 50% active factor (duty cycle) using 555 IC, we can use two diodes to separate the charging and the discharging path. With no diodes, we can also generate 50% duty cycle using 555 IC by configuring the circuit as shown in the schematic diagram. The high state period is similar to regular configuration, t1 = 0.693 RA C, […]
