Question { Ericsson, 30838 }

highest voltage gain can be obtained from


a ).CC


b).CE


c).CB


d).Both CE and CB

Answer

guys am not contradicting any answer stated above, i accept it totally..
a doubt..
is it not the resistors connected at either ends decide the v gain in cb case..
i mean the ip n op voltages -- wont they b the same if the same values of resistors r used either side( or would the transistor go off to cut off ?? if same values r connected on either sides)

How many types of Registers are there in 8086
Microprocessors?

Answer

it actually depends on a way a person interprets it ..
can be classified as general purpose registers(GPR s) and special function registers (SFR s)..
or in specific to 8086--
1. general registers (AX, BX, CX, DX)
2. index and pointer registers (DI, SI, BP, SP)
3. flag register
4. segment registers(CS, DS, SS, ES)

Question { 39732 }

why is 555 timer called so?

Answer

inside the 555 timer, there are 3 resistors used in series to get vcc/3 and 2*vcc/3 ....
all the 3 resistors used are same and are 5k ohm resistors..
so its called 555 timer..
acknowledgement guys ... am kinda sure though, but plz verify it ...
