We found this circuit in a 1977 Timers Cookbook. The circuit uses common components to divide a 1 kHz signal by 2. The output has an amplitude of 2 Vpp.
We found this circuit in an old documentation from the 70s. The sensor is an LDR that must be...
This low noise audio amplifier stage uses only one transistor and has a high enough gain to...
In fact, the 556 consists of a double 555, which can be replaced by these integrated ones. The...
