From an audio amplifier standpoint, transistors were primarily low-voltage, high current devices. Since loudspeakers were typically low-impedance, the transistorized circuit didn't require a transformer to help match the impedance; i.e. they were better matched. However, when a transistor "saturated" it "clips" abruptly, causing harmonics at the output. Vacuum tubes tended to "soft clip' which reduced the undesirable harmonics.
From another standpoint, transistors were smaller in size, didn't require high voltage power supplies, and dissipated less heat (i.e. more efficient).
What else can I help you with?
Are transistors very large compared to the other valves used in apple macs?
Apple Macs don't use valves (computers haven't used valves since around 1955). However, transistors are very much smaller than valves (by several orders of magnitude), are much more reliable, are cheaper to mass produce and offer much greater efficiency.
Advantages of npn over pnp transistors?
because of high output drive,easy to manufacture and takes less space and also low power consumption...
What are the advantages of collector to base biased?
it converts it to a diode. sometimes this is done for matching the characteristics of diodes and transistors in the circuit. standard diodes might not have similar enough curves to the transistors for the circuit to operate correctly.
What is the use of a turbine in refrigeration?
It is used as a compressor. It has the same advantages over a piston compressor as a gas turbine engine has over a piston engine. i.e. no valves, much lower part count and much greater efficiency.
Why thyristors are preferrred over transistors?
Thyristors are preferred in applications that require the characteristics on a thyristor. Thyristors are quite different to transistors, when they turn on, they stay turned on untill the power source is removed. Transistors conduct as controlled by the emitter current.
What are the advantages oe transistors over vacuum tubes?
6u76yu
What are the advantages of TTL over DTL?
because the amplifying function are performed by transistors (contrast with RTL and DTL).
What are the advantages of using presta valves over other types of valves?
Presta valves have advantages over other valve types because they are lighter, more aerodynamic, and allow for higher tire pressures. They also have a smaller diameter, making them compatible with narrower rims.
Are transistors bigger or smaller than valves?
Yes they are. The invention of the transistor signalled the end of large, bulky valves in circuits. Modern transistors are so small - that thousands can be housed on one microchip.
What component replaced valves in the second generation computer?
discrete transistors
Why did the colossus need valves?
Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.
Are transistors very large compared to the other valves used in apple macs?
Apple Macs don't use valves (computers haven't used valves since around 1955). However, transistors are very much smaller than valves (by several orders of magnitude), are much more reliable, are cheaper to mass produce and offer much greater efficiency.
What are 3 advantages of transisters?
I will assume you mean "transistors". Compared to their predecessors (vacuum tubes), transistors:* Are faster * Use less current * Use less space Note that all of these advantages get even more pronounced in the case of integrated circuits (which also contain transistors).
What are the advantages of using a mountain bike with a Presta valve over other types of valves?
Mountain bikes with Presta valves have advantages such as better air retention, compatibility with high-pressure tires, and a smaller valve size for easier inflation.
Advantages of npn over pnp transistors?
because of high output drive,easy to manufacture and takes less space and also low power consumption...
