Ac/Dc Indicator
This circuit utilizes two switching transistors and two LEDs to differentiate between low-level AC and DC signals. A lit red LED indicates a positive DC signal, while a lit yellow LED signifies a negative DC signal. If the input signal...
Sine to Square Wave Converter
This schematic example demonstrates a sinusoidal voltage input at a frequency of 10 kHz, which is converted to a square wave using an inverter-based circuit. The VDD and VSS rails are connected to +1V and -1V, respectively. The control file...
VOLTAGE TO FREQUENCY CONVERTER + 1uS LED PULSE DRIVER
This circuit receives the signal from the amplifier and emits powerful 1μs infrared light pulses from a low-cost LED, which are frequency modulated by the audio information. The 10kHz center frequency of the pulse stream is sufficiently low, allowing a...

Simple Wwv Converter For Auto Radios Circuit
This simple frequency converter mixes the 15-MHz WWV/WVH signal with a 16-MHz signal from the local oscillator (LO) to convert it down to 1 MHz, enabling it to be received on an AM-band receiver.
The frequency converter operates by utilizing a...
10MHZ to 1MHz converter
This circuit is an oscillator at frequency 10MHZ, using IC 1A and IC1B and a frequency divider. Using the IC2 it divides the pulses to 10. IC1C is a buffer. The variable capacitor 39pF is microtuning the frequency. The pin...
Mixer Converter Circuits
In 2011, designing a frequency converter circuit typically involves selecting an integrated circuit (IC) that meets specific requirements regarding gain and mixer spurious products, along with adding a couple of filters and a power supply. Often, the oscillator is integrated...
