Hi,
I am aware that DSP and control systems are two branches of the broad topic 'Signals and Systems'.
I'm thinking of pursuing an advanced degree in either of the mentioned topics.
But I am unable to decide between the two. Can anyone please describe a normal day in the life of dsp...
Hi,
I got a new PIR sensor (lhi 968) and tested it. The following are the connections that I made
GND pin : ground
D pin : +5V dc supply
S pin : CRO (to view the output)
But no matter how I tried to trigger the circuit (waving hands, blowing air, boogie dancing) the sensor gave a constant...
Hello,
Most portable cd players (discman....or rather discmen :shock:) work with 2 AA batteries (each of 1.25V).
The arrangement that we need is this:
The +5V TTL signal from a microcontroller (80c51) should power the discman i.e we need some arrangement such that the output from the...
Thanks guys, more inputs from other members will turn this into a one-stop destination to find the titles of these special books (which are hard to track down). Try googling 'fun electronics books' and you'll know what I mean.... 8-) No unauthorized links please ;-)
Hi,
Please mention a few electronic/electrical engineering books that are written in a light vein and are fun to read. Something along the lines of the 'Dummies' series. Please mention the titles of the books ONLY.
Hi doraemon !
Is this what you're saying?
Generate TTL logic level serial signals from the MCU (can be done easily). Convert these signals to RS232 using MAX 232. Result will be RS 232 signals. This could work because we don't care how we get the RS232 signals. We just want them ...
Hello,
Operation: Converting an RS 232 signal to TTL signal
Description: I know this can be done using the IC MAX232
Problem: I'm searching for a simple device that gives RS 232 signals as output. Please note that the device's pins should be such that it can be connected to the IC on a...
Thank you Shaiko.....
Yes, these are the main fields I'm interested in. Definitely FPGA/ASIC design has captured my interest....
But most MS programs include this in a domain called 'Computer Engineering' and this domain invariably includes some computer science courses like software...
yello,
I'll come straight to the point. I want to pursue a masters in electrical engineering in a field that is the intersection of
a) digital systems and logic design
b) control systems
c) dsp (in particular digital filter design)
Please suggest a field (or a closely related one) that...
When we write H(e^jw) we mean a function of e^jw.
But e^jw is itself a function of the variable w. Hence we may write H(e^jw) as H(w)
But to be more clear H(e^jw) is preferred.
I am sure there are biomedical instruments for this purpose.
As you may know, a signal (say a man's heart beat) will be composed of a number of sinusoids of harmonic frequencies with different weights to each frequency. To measure this we may connect the instrument measuring the heart beat...
