On an old fashioned bench a signal generator was once an indispensable instrument, but has now largely been supplanted by the ...

You can build a simple 1KHz square wave generator using a few components and the LM3909 that is useful for testing audio equipment. It is powered from a single 1.5V battery cell and the maximum ...

To prevent the temperature and voltage supply from affecting the frequency of the square wave generator, the oscillator freq. fo must be smaller than 1/2tpn where: tp = average delay time of each gate ...

When [Miroslav] sent in his ‘guerilla homebrew’ square wave generator, we were really impressed. With a relatively simple schematic that uses parts that could be salvaged from old radios, this ...

The simplified block circuit shows IC1 operating as a square-wave generator with frequency determined mainly by R1 and C1 (Fig. 1).

1. This very-low-frequency sine- and square-wave generator requires few components, but provides low-distortion outputs (derived from LTspice simulator). The output of op amp U1 is applied to the ...
