plz tell me how CLI display number from analog phone line . when we dial a number how our number goes to other party CLI. plz provide me a CLI circuit which collects information (calling party phone number) from analog telephone line.
equivalent dc voltage
i have AC voltage between 1V and 6V. i want its equivalent DC voltage . if AC voltage changes between 1V and 6V then at output equivalent DC voltage occurs.
how ADC take AC voltage
i m using ADC 0804. plz tell me the circuit for connecting AC voltage to ADC input. further more i have 220/5V transformer. can i connect transformer output (5V) to ADC input. At 220V frequency is 50 hz. i m step downing 220v Ac to 5V AC using transformer. can...
i have 6V AC and i want 5V AC . plz tell me the circuit for taking 5V ac at output and input is 6V ac. i m giving this 5V Ac to an analog to digital conerter circuit .
i m taking 6V AC from 220V to 6V transformer. so plz tell me that how I got 5V ac for an ADC input so that the current is as...
plz give me a circuit which receive a serial data and output 2 parallel bits at a time
ie if serial data is 11 10 10 00 then it output two parallel bits as first 00 then 10 then 10 then 11 . the output is 2 bits at a time
plz tell me how can i calculate Volatge (rms) from peak value of voltage . how can the KWH be calculated using power formula (V*I). how one unit drops in electric meter . i have value of current and voltage how i can calculate apparent and true power and how KHW can be calculated from voltage...
electric meter principle
Plz tell me
How the unit of electric meter drop by which criteria not using Revolution of disk of meter but using how much current is consume by the home device
how unit of electric meter drop base on principle of how much current is used by the home appliances
in...
basically i want 4 different voltages level to be assigned. now the four different levels must be +5, +3, -3, -5. now i am unable tyo do this because the operational amplifier is not working as its layout specifies. please guide me for both inverting and non-inverting behavior.
i am using 8051 microcontroller along with external memory. as port 0 and port 2 are for external memory address . i have interfaced analog to digital converter (ADC 0804) output to port 0 of microcontroller . as port it can both handle address and data plz give me a small code for reading...
at28c256 programmer
how can i erase EEPROM AT28C256-PI . i have a genius programmer but it does not erase it , i can only program it by GENIUS programmer . so how can i erase this EEPROM
can anyone give me a small C language code for 8051 microcontroller . the code is stored in EPROM 27C256 and only give number 2 on port one.The code should run from EPROM
