i read that pnp tr . are suitable for switch so, i want to know why ?Why do you think it would be?
Is this a homework question?
yes both can be used but which one will be best to use ...both are suitable, just differnt polarity.
A FET is usually preferred, but I wouldn't say an NPN BJT is "not suitable". It can perform just fine as a switch. If you have just 1V to put on the base or gate, it's the best game in town.why npn tr not suitable as switch for analog signals
A BJT can work well as a digital or power switch. But you should note that the offsets of a BJT can be problematic in low level analog signal switching.A FET is usually preferred, but I wouldn't say an NPN BJT is "not suitable".

Not in integrated form, but you could conceivably make one from discretes.Unless OP is talking about an analog switch like CD4066, then I have to say I havent seen one made with bipolar transistors. Do such even exist?
The more you put into your question the better folks will be able to help and the more you will get out.why npn tr not suitable as switch for analog signals
