What is the application of square wave generator?
Square wave generators are generally used in electronics and in signal processing. It is just like a Schmit trigger circuit in which the reference voltage for the comparator depends on the output voltage. It is also said to be an astable multivibrator.
What is square wave generator?
The square wave generator is defined as an oscillator that gives the output without any input. The square wave generator is also known as Astable Multivibrator or free-running and the frequency of the square wave generator is independent of the output voltage. …
What is square wave generation?
What is the role of square wave generator Mcq?
Explanation: Square wave outputs are generated where the op-amp is forced to operate in saturated region, that is, the output of the op-amp is forced to swing repetitively between positive saturation, +Vsat and negative saturation, -Vsat. Explanation: The differential output voltage Vid = Vin1 – Vin2= 3-7v = -4v.
What is CJNE?
The CJNE instruction compares the first two operands and branches to the specified destination if their values are not equal. If the values are the same, execution continues with the next instruction.
Which method is used for converting digital to analog signal by DAC0808?
There are two methods of converting digital signals to analog signals. These two methods are binary weighted method and R/2R ladder method. In this article we will use the MC1408 (DAC0808) Digital to Analog Converter. This chip uses R/2R ladder method.
What is a square wave generator in Mcq?
Explanation: An astable multivibrator is one which does not have any stable state. It has two quasi-stable output states which keep toggling at regular intervals. The output waveform is thus a square wave and this circuit is also called a square wave generator or a free running oscillator.
What is the difference between 8085 and 8086 microprocessor?
8086 is 16 bit microprocessor whereas 8085 is 8 bit microprocessor. 8086 has 20 bit address bus while 8085 has 16 bit address buss. 8086 supports multiplication and division, whereas 8085 doesn’t support this job. 8086 operates in two modes, whereas 8085 operates in single operating mode.
How to generate square wave with Intel 8085?
Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to generate pulse waveform. Write 8085 Assembly language program to generate continuous square wave. To generate square wave with 8085, we will rotate 10101010 (AAH) continuously.
How to write program to generate continuous square wave?
Problem – Write a program to generate continuous square wave. Use D 0 bit to output the square wave. The required waveform is: The alternate pattern of 0/1 bits can be provided by loading the accumulator with AAH (10101010) and rotating the pattern once through each loop.
What does Sim mean in the 8085 instruction?
Let’s look at the SIM instruction first. SIM means Set Interrupt Mask. SIM is a multipurpose instruction, which is used for, To mask or un-mask RST 7.5, RST 6.5, and RST 5.5. To send data out serially through SOD of µP. SOD is the 4th pin of 8085. To reset RST 7.5, without considering it’s masked or not.
Which is the waveform for the square wave?
Use D 0 bit to output the square wave. The required waveform is: The alternate pattern of 0/1 bits can be provided by loading the accumulator with AAH (10101010) and rotating the pattern once through each loop. Bit D 0 of the output port is used to proved logic 0 and 1. Therefore, all other bits can be masked by ANDing the accumulator with 01H.
