The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of -55潞C to +150潞C and a accuracy of 卤0.5潞C . The output voltage is 10mV/潞C . The output voltage is converted by the AD convertor of ...
this is a digital intercom projects using ADC PWM and UART interrupt.
you take the value from mic enter it to ADC and then send serially to the other microcontroller which receives the data and transform the digital data into analog data by PWM which is connected to speaker
Video-DVM is a very cheap DVM that shows how an output as complex as a videocomposite signal can be generated entirely in software: two I/O pins and three resistors are all the hardware required. Connected to any TV set it displays voltages, included max and min peaks, using both giant digits and an ...
This is schematic and Gerber files of PCB that is used for GPS tracking device with GSM link. Scheme has many valuable schematic features, like protected digital and analog I/Os, power part adapted for car power supply, etc.
Can be used as a reference design for anyone who wants to make own GPS GS ...
In C Algorithms for Real-Time DSP, author Paul M. Embree presents a complete guide to digital signal processing techniques in the C programming language. This book is structured in such a way that it will be most useful to the engineer who is familiar with DSP and the C language, but who is not nece ...
Digital Modulation Techniques are those echniques through which we convert digital signals into analog signal which can be transmitted through transmission medium...this program demostrate some of the basics techniques
Title : Implementation of quadrature modulation and demodulation
Design Object : By implementing quadrature modulation and demodulation of analog signals in digital signal processing, students will have better understanding of sampling and frequency analysis of discrete-time signals.
