Microcontroller Projects: Processing explanation of Ultrasonic Range Meter

http://8051pic.blogspot.com/2010/09/processing-explanation-of-ultrasonic.html

My First Microcontroller Blog. Processing explanation of Ultrasonic Range Meter. His range meter detects a reflected wave from the object after sending out a ultrasonic pulse. By measuring the time which returns after emitting a sound wave, a distance to the object is measured. The operation of the following figure is repeatedly executed. LED display processing is executed in parallel with this operation. Label Definition * * * * * * * * * *. Send-out pulse count adr. Environment designating and others.

Microcontroller Projects: Basic Visible and Infrared Light Detectors

http://8051pic.blogspot.com/2010/05/basic-visible-and-infrared-light.html

My First Microcontroller Blog. Basic Visible and Infrared Light Detectors. This page features basic, visible light photo-detector circuits that can be used to detect trains or other light blocking objects. The phototransistor or photocell would normally be placed between the rails in the circuits on this page. The Photo-detectors on this page use LM339 (Quad) or LM393 (Dual) voltage comparator, integrated circuits to detect the change in voltage across the sensor. Visible Light Photo-Detector Circuits.

http://8051pic.blogspot.com/2010/09/circuit-explanation-for-ultrasonic.html

My First Microcontroller Blog. Circuit explanation for Ultrasonic Range Meter. The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages. It is 100 times at the first stage (40dB) and 10 times (20dB) at the next stage. As for the dB (decibel), refer to " Logarithm Table. As for the operation of the operational amplifier, refer to " Operation explanation of the triangular wave oscillator. At the circuit thi...

Audio - ClassD: Class D Amplifiers: Fundamentals of Operation

http://audio-classd.blogspot.com/2010/10/class-d-amplifiers-fundamentals-of.html

Saturday, October 30, 2010. Class D Amplifiers: Fundamentals of Operation. In the past, the power-efficiency advantage of classical PWM-based Class D amplifiers has been overshadowed by external filter component cost, EMI/EMC compliance, and poor THD N performance when compared to linear amplifiers. However, most current-generation Class D amplifiers utilize advanced modulation and feedback techniques to mitigate these issues. The Basics of Class D Amplifiers. In mathematical terms, this means that:.
