The present invention is generally directed to a communication system and, more specifically, to a communication system that includes a single receiver system that receives amplitude shift keying ASK messages and frequency shift keying FSK messages simultaneously. Today, increasingly, motor vehicle manufacturers are adding radio frequency RF receiver functionality to motor vehicles in order to receive various information, e. RF receivers for tire pressure monitoring TPM systems are similar to RF receivers used in remote keyless entry RKE systems, which have been implemented in motor vehicles for approximately a decade.

Amplitude Shift Keying

Want to add wireless capabilities to your next Arduino project, for less than the price of a cup of coffee? They can often be obtained online for less than two dollars for a pair, making them one of the most inexpensive data communication options that you can get. And best of all, these modules are super tiny, allowing you to incorporate a wireless interface into almost any project. This little module is a transmitter among two. It is really simple as it looks. The heart of the module is the SAW resonator which is tuned for

In this project, I will use RF modules with Pic 16fa. It will be a short tutorial about rf. After you learn ho rf modules communicate with each other you can use these modules with pic microcontroller, ardunio or any microcontroller. In short term, radio frequency RF refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to GHz, as well as the alternating currents carrying the radio signals. We need two modules which are transmitter and receiver. Our control our data 1 and 0 we use the microcontroller in this project and transmitter send these data in Seri way in radio waves.

Amplitude-shift keying ASK is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave. In an ASK system, a symbol , representing one or more bits , is sent by transmitting a fixed-amplitude carrier wave at a fixed frequency for a specific time duration. For example, if each symbol represents a single bit, then the carrier signal will be transmitted when the input value is 1, but will not be transmitted when the input value is 0. Any digital modulation scheme uses a finite number of distinct signals to represent digital data. ASK uses a finite number of amplitudes, each assigned a unique pattern of binary digits. Usually, each amplitude encodes an equal number of bits.

In an embedded system it is often desirable to communicate with another device wirelessly. This wireless communication may be accomplished through optical communication or through radio-frequency RF communication. For many applications, the medium of choice is RF since it does not require line of sight. RF communications incorporate a transmitter and a receiver. They are of various types and ranges. Some can transmit up to feet. RF modules are widely used in electronic design owing to the difficulty of designing radio circuitry.

Wireless Communication in any form has become an essential part of human life whether it may be short distance T. V Remote or long distance radio communication. Wireless communication is all about transmission of data wirelessly so that there is no hassle of any wires and no direct contact with the device itself. Arduino on the other hand, is a low cost solution for microcontroller applications with open source hardware and software. Arduino can be used in many small to real time applications with simple programming and hardware components. By combining the two objects i. In this project, we are going to design a system in which two Arduino boards will communicate with each other using RF Module.

Amplitude Shift Keying ASK is a type of Amplitude Modulation which represents the binary data in the form of variations in the amplitude of a signal. Any modulated signal has a high frequency carrier. The binary signal when ASK modulated, gives a zero value for Low input while it gives the carrier output for High input. The ASK modulator block diagram comprises of the carrier signal generator, the binary sequence from the message signal and the band-limited filter. Following is the block diagram of the ASK Modulator.


An ASK transmitter and receiver chipset using 40 nm. CMOS technology for wireless communication systems is described, in which a maximum data rate of

 Джабба, - проворковала женщина в ответ.  - Это Мидж. - Королева информации! - приветствовал ее толстяк. Он всегда питал слабость к Мидж Милкен.

 Линейная мутация, - простонал коммандер.  - Танкадо утверждал, что это составная часть кода.  - И он безжизненно откинулся на спинку стула.

 - Хейл - это… Сьюзан замерла. Должно быть, это какая-то ошибка. Следопыт показывал адрес, не имеющий никакого смысла.

Но коммандер поймал ее взгляд и нахмурился. Значит, это не Дэвид. Сьюзан почувствовала, что у нее перехватило дыхание. Она лишь хотела знать, что человек, которого она любит, в безопасности. Стратмор, в свою очередь, тоже сгорал от нетерпения, но подругой причине.

 - Я… я не могу. Дэвид даже вздрогнул. Он смотрел в ее глаза, надеясь увидеть в них насмешливые искорки.

Его массивная шея зажала ей рот, и Росио чуть не задохнулась. Боже, поскорей бы все это закончилось, взмолилась она про. - Si. Si! - вскрикивала она в интервалах между его рывками и впивалась ногтями ему в спину, стараясь ускорить его движения. Все смешалось в ее голове - лица бесчисленных мужчин, склонявшиеся над ней, потолки гостиничных номеров, в которые она смотрела, мечты о том, что когда-нибудь все это кончится и она заведет детей… Внезапно, без всякого предупреждения, тело немца выгнулось, замерло и тут же рухнуло на .

 Вашей возлюбленной пятнадцать лет. - Нет! - почти крикнул Беккер.  - Я хотел сказать… - Чертовщина.  - Если бы вы согласились мне помочь. Это так важно.

Он закрыл глаза и постарался сползти на скамье как можно ниже: он единственный в церкви был не в черном. Откуда-то донеслись звуки песнопения. В задней части церкви между скамьями продвигался человек, стараясь держаться в тени.

 Мы тонем! - крикнул кто-то из техников. ВР начала неистово мигать, когда ядро захлестнул черный поток. Под потолком завыли сирены. - Информация уходит. - Вторжение по всем секторам.

A superheterodyne receiver , often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency IF which can be more conveniently processed than the original carrier frequency.
