Colpitts oscillator FM transmitter
Its frequency depends on the capacitance of the vary cap diode. The center frequency is changed by varying the biasing voltage of the vary cap through the 47K pot. You can use a 75cm telescopic antenna or simply a length...
Self Powered Sine Wave to Square Converter
This circuit utilizes a single active component, the 4069 IC, to convert sine waves into square waves without requiring an external power source. It is designed for testing audio instruments.
The circuit leverages the characteristics of the 4069 IC, which is...
sine to square triangle wave
If a triangle wave signal or a square wave is required but only a sine wave generator is available, this converter can be utilized to simplify the process. The circuit consists of two integrated circuits (ICs): an LM13700 and a...
450 800Hz signal generator circuit diagram
The 450/800Hz oscillation circuit depicted in the figure utilizes transformer coupling. The frequency conversion is achieved by varying the inductance through a variable filter tap (T1). When the switch control signal (S) is set to position 1, the oscillator circuit...
High Power Square Wave Generator (0-500V 25A)
V1 and V2 are set to 5V in the simulation, but they could also be set to 10V to eliminate the need for a second power supply. Alternatively, if logic level FETs can be sourced at that higher voltage, the...
