335_LOW FREQUENCY DOUBLER. (Simulide R2116 or higher.)
This frequency doubler is based on converting the rising or falling edges into narrow pulses (given by the delay of the gates involved in their extraction). This doubler is designed for low frequencies, but by properly adjusting the RC network higher frequencies can be reached.
SCHEME:
The rising edge pulse is obtained with an AND gate and an inverter. The falling edge pulse is obtained with a NOR gate and an inverter. Both pulses are added and applied to a T-type flipflop at whose output there is an RC delay network to obtain a widening of the output signal and make an eventual tuning with the input frequency. This structure (FF, RC delay and inverter) forms a simple monostable with rising edge triggering. An LED at the FF output acts as a monitor.
This doubler is implemented in a subcircuit added to the attached Zip. Four of its components have been set as "exposed" for adjustment from the outside to the subcircuit.
SUBCIRCUITS:
This example integrates several subcircuits located in the "data" folder into the ZIP attached. This folder must always be next to the "sim1" scheme so that it can be executed. A subcircuit is a "custom" circuit that accumulates a set of Simulide base components (primitive function) to obtain a new or an adapted function. These subcircuits are treated by Simulide as another component of its own structure. User can create his own subcircuits or use the ones published here in your own designs once the procedure is known, explained in detail in the Simulide tutorials: https://simulide.com/p/subcircuits/
