posts - The primary advantage of digital transmission over analog transmission is Noise Immunity. A digital signal (in comparison to an analog signal) is. In addition, specific models mentioned in the spying forum Like MFJ Frequency Counter, and more are here for future reference. MFJ, Aceco Frequency Counter, and Optoelectronics frequency Counter, and more sold here,we update our stocks to keep in touch with modern improvements in Frequency Counter design.
The second easiest way is to use a 16F pic and build a frequency counter based on this chip. There are many design based on this and you can just google "16F frequency counter" and you'll be able to find one. The next easiest way is to build this old 3-chip design from Radio Electronics Dec issue. Texas Instruments is pleased to present the High Speed Analog Design and Applications Seminar to our High Speed customers. This material represents some innovative investigations into problems plaguing analog designers, as well as some straight forward explanations of fundamental analog principles and design techniques.
A NAND gate-only frequency counter. A six-digit frequency counter with leading-zero suppression implemented entirely in NAND gate logic. Complete I.C. complement: * 74HC00 quad NAND gate; 1 * 74HC quad NAND gate with schmitt-trigger inputs; 1 * B quad NAND gate (used in analogue mode as the signal-input pre-amplifier). Counter is a digital device and the output of the counter includes a predefined state based on the clock pulse applications. The output of the counter can be used to count the number of pulses. Generally, counters consist of a flip-flop arrangement which can be synchronous counter or asynchronous counter.

Electrical engineers will find High Frequency Measurements and Noise in Electronic Circuits an essential desktop reference for information and solutions, and engineering students will rely on it as a virtual source book for deciphering the "mysteries" unique to high frequency Cited by: Design of a high noise immunity analog frequency counter / By Mark Christian.
Loessel. AbstractAuthor: M. Loessel. These devices are divide-by-N down-counters that can be programmed to divide an input frequency by any number "N" from 3 to 15, The output signal is a pulse one clock cycle wide occurring at a rate equal to the input frequency divide by N.
The down-counter is preset by means of 16 jam inputs. Analog High Speed Coupler, High Noise Immunity, 1 MBd, 15 kV/μs DESCRIPTION The SFH is an optocoupler with a GaAlAs infrared emitting diode, optically coupled to an integrated photo detector consisting of a photo diode and a high speed transistor in a DIP-8 plastic package.

system ground at the VCC bus is required for best noise immunity. Also. frequency counting techniques, familiar speed/accuracy tradeoffs can be averted. Since an analog quantity represented as a frequency is inherently a serial data stream, it is easily handled in large multichannel systems.
Frequency information can be trans-mitted over long lines with excellent noise immunity using. Noise Immunity. the ability of an apparatus or system to perform its functions when interference (noise) is present.
Noise immunity is rated according to the noise intensity at which the disruption of the equipment’s functions is still within permissible limits. The higher the level of noise at which the equipment maintains its operating ability.

This book is the fourth of aseries dedicated to 4/4(1). If a linearly-proportional analog output voltage is required, the counter can be replaced by a TC used in the F/V mode.
HIGH NOISE IMMUNITY DATA TRANSMISSION When transmitting analog data over long distances, it is advantageous to convert the analog signal into a digital signal, which is less susceptible to noise pick-up.
The design of a unique analog frequency counter is described. Frequency response is not as high as some counters currently on the market, being only 0 to kHz. An analog output and a digital readout can be readily obtained. The range of the instrument is from zero to fc Ã Hz, where fc is the clock frequency.
In the programmed synchronous power-down, the device power-down is gated by the charge pump to prevent unwanted frequency jumps. Once the power-down is enabled by writing 1 into the PD1 bit (provided that 1 has also been loaded to PD2), then the device goes into power-down during the next charge pump Size: KB.
The Analog Comparator triggers the event when the input signal is greater than mV. With a bias resistor on pin 5 the trigger threshold is toggled to get better noise immunity which works similar like a Schmitt-Trigger circuit.
The picture shows how a sine wave is detected by the Analog Comparator. With more illustrations, examples, and worked problems, High-Frequency and Microwave Circuit Design, Second Edition provides engineers with a diverse body of knowledge they can use to meet the needs of this rapidly progressing field.
The book details the modulation and demodulation of circuits and relates resonant circuits to practical needs. The TC converts the input voltage into a pulse or square wave which is transmitted on a pair of wires by use of a line driver and receiver in the following system.
At the other end, we can digitally displayed the original voltage (Vin) on a frequency counter or converted back to an analog voltage by use of a TC F/V converter. Flicker noise is modeled by a noise current source in parallel with the device. The rms flicker noise current in the frequency band Af is given by (7) where I is the dc current, n N 1, Kf is the flicker- noise coefficient, and m is the flicker-noise exponent.

Radio Hobbyist’s Designbook or RHdb (for short) was designed to guide you into design of electronics apparatus that relates to radio. It assumes you know something about electronics but you can skip Chapters which cover familiar subjects.
Mathematics needed in design is down to simple algebra and trigonometry.The MLQ1xx/MLQ1xx MCUs feature low power consumption with high noise immunity, making them ideal for industrial equipment as well as consumer electronics. The MLQ1xx of high performance CMOS MCUs adopt LAPIS Semiconductor's unique RISC-type U16 Core 16bit CPU, while the MLQ1xx utilizes the U8 8bit core for lower power consumption.Analog High Speed Coupler, High Noise Immunity, 1 MBd, SOP-5 Package DESCRIPTION The VOM and VOM, high speed optocouplers, each consists of a GaAlAs infrared emitting diode, optically coupled with an integrated ph oto detector and a high speed transistor.
