INVERTER_AND_PULSE_STRETCHER
The circuit samples the output of a multiplexer and provides the necessary current for driving a transfluxor in an analog-to-digital converter that generates a six-bit binary Gray code. -N. Aron and C. Granger, Analog-To-Digital Converter Uses Transfluxors, Electronics, 35:20, p...
TIPE Project
A simple non-commercial grade multiplexer compatible with telephones. It will support four telephone lines and will multiplex over one cable. The topic was free of choice but had to be oriented around the theme of "PrG©vision" (prediction). As anticipated, the...
Transmitting audio over laser or LED
This circuit transmits audio information using light waves. It employs amplitude modulation (AM) to vary the intensity of an LED, which is detected by a cadmium sulfide photocell that changes its resistance based on light intensity. The circuit includes two...
2-to-1 Multiplexer
The 8-bit 2x1 multiplexer comprises 16 tristate buffers and a static inverter. It is configured such that when the select bit is low, 8 of the input bits are transmitted through the tristate buffers to the 8 output bits. Conversely,...
REMOTE CONTROL CIRCUITS
The circuit utilizes a 4-bit encoder to generate data, which is then modulated using an RF modulator for transmission. On the receiving end, the signal is demodulated, and a decoder retrieves the 4-bit data. The pin configuration for the HT12E...
Deviation Meter
A deviation monitor can be constructed by connecting a frequency modulation (FM) detector to an AC voltmeter, calibrating the meter in units of frequency deviation. One method for detecting or demodulating the FM signal is via a phase-locked loop (PLL)....
Interpolating Scanner Circuit
This design is for an interpolating scanner, a circuit featuring multiple signal inputs, a control voltage input, and a signal output. The output selectively transitions between inputs, smoothly fading from one to the next as the control voltage increases. A...

0 to 10V output multiplexer measuring circuit
The 1832 low drift input has a temperature coefficient of 0.07 µV/°C (RTI, G 500) and exhibits excellent linearity with a maximum deviation of 0.005%. It can drive resistive loads greater than 120 ohms in a bridge excitation circuit, with...
