What is Fast PWM AVR?
The fast PWM is used to generate a pulse train with varying duty-cycle. • The PWM output is generated on the OC1A output pin (PB1) • An analog filter can be used to shape the digital PWM output to obtain.
What are the different PWM modes?
Duty Cycle of a PWM waveform is given by the following relation.
- There are three modes of PWM operation – Fast PWM, Phase Correct PWM and Frequency and Phase Correct PWM.
- How to choose timer, operation mode and compare output mode for generating the desired PWM.
How many PWM outputs does the Atmega 16 have?
Atmega16 has four dedicated PWM pins.
What is PWM technique?
Pulse width modulation (PWM) is a modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. The output switching transistor is on more of the time for a high-amplitude signal and off more of the time for a low-amplitude signal.
What do you mean by pulse modulation?
Definition of pulse time modulation : modulation of the time intervals between successive pulses of constant duration and amplitude in accordance with a signal specifically : a system of multiplex high-frequency transmission using this method of modulation.
Why Atmega16 is used?
Atmega16 is preferred over other microcontrollers like Atmel 8051 because it comes with much faster ability to execute instructions and consist of modified RISC processor. It has a built-in flash which comes with features of a bootloader. It has built-in 10-bit ADC, SPI, PWM, and EEPROM.
