Can I use a 2.5V voltage regulator IC (such as LM336-2.5) for 'REF' supply?
My input signal voltage range will be between 1V to 2V

In the 1st schematic, the capacitor C2A is connected between (+) terminal of opamp and "REF" where I will connect a 2.5V voltage regulator o/p...
Hi,
I want to design an active Sallen-Key 2nd order low pass filter with single supply opamp. I am using OP213 from AD with +5V and 0V as the supply voltage.
Cutt-off frequency: 2kHz
Gain: 10 (V/V)
I designed the below circuit using AD filter design tool and connected 2.5V for Vref from a...
I want to design the digital circuit in such a way that it should take value of X automatically which means even if the morse code symbol rate varies, the detector should detect the dot, dash, character space and word space correctly
I'm also using the same approach (adding 0 for dot and 1 for dash to a shift register with an initial value of 00000001).
But the problem is with detecting counts of dash and dots.
Here is the program I have written as of now:
library ieee;
use ieee.std_logic_1164.all;
use...
I want to implement a Morse code to ASCII converter in vhdl and then to transmit that ASCII character to PC terminal through UART. I have completed the UART part.
But i don't know how to implement the converter part. The problem is with varying symbol rate of input Morse code. I want to detect...
Hi
Could someone give following details regarding Communication protocol used in Remote Keyless Entry in cars:
Operating frequency
Range
Protocol
Licensing required?
The range of current system is upto 100m. But if I want to increase the range to 1000m for some other applications, is it...
But in many places I have read that the wave will not be reflected since its wavelength is larger than the object and wave will be reflected since its wavelength is smaller than than the size of object. But I don't know the technical background.
Ex: Millimeter wave penetration through rain...
Most of us knew that FMCW Radar is being used in Automotive applications to measure distance and relative velocity of the vehicle going in front.
I'm not able to understand how the oncoming vehicle (vehicle coming in opposite direction of the subject vehicle) is differentiated from vehicle...
For example, take the two below situations:
1) A radar wave of wavelength 5mm is striking a perfect metal sphere of diameter 3mm
2) the same radar wave hits a perfect metal sphere of diameter 8mm
In which case/cases the radar wave will get reflected and why?
Guys, can yu please help me in explaining the relation between object size and wavelength of EM wave with respect to reflective property of the wave when it strikes the object.
Is it like if the wavelength is smaller than the object size then the wave will be reflected and vice versa?
