Function of ic 7490 decade counter?
The function of an IC 7490 Decade Counter, which is a computer chip, is to pin cycles 0 to 9 through QA, QB, QC and QD which are 4 bits in a binary number. The IC 7490 Decade Counter produces an output pulse for every ten input pulses.
Working of IC 4017?
4017 is a decade counter having 10 output pins with different functions. When a source of pulses is connected to the clock input by unstable circuit of any timer IC applied to the reset and disable input. One of the individual output is high at a time. thanx......

When Tim pushes the wire between the poles of the magnet the galvanometer registers a pulse When he lifts the wire another pulse is registered How do the pulses differ?
The pulses differ because the two pulses are in opposite directions.
What is the advantage of ppm over pwm and Pam?
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
Explain the Working of 3 bit synchronous counter?
It can be seen that the external clock pulses (pulses to be counted) are fed directly to each J-K flip-flop in the counter chain and that both the J and K inputs are all tied together in toggle mode, but only in the first flip-flop, flip-flop A (LSB) are they connected HIGH, logic "1" allowing the flip-flop to toggle on every clock pulse. Then the synchronous counter follows a predetermined sequence of states in response to the common clock signal, advancing one state for each pulse. The J and K inputs of flip-flop B are connected to the output "Q" of flip-flop A, but the J and K inputs of flip-flops C and D are driven from AND gates which are also supplied with signals from the input and output of the previous stage. If we enable each J-K flip-flop to toggle based on whether or not all preceding flip-flop outputs (Q) are "HIGH" we can obtain the same counting sequence as with the asynchronous circuit but without the ripple effect, since each flip-flop in this circuit will be clocked at exactly the same time. As there is no propagation delay in synchronous counters because all the counter stages are triggered in parallel the maximum operating frequency of this type of counter is much higher than that of a similar asynchronous counter.

What is countering?
A counter is a sequencial circuit with a set of flip flop which counts the number of pulses given at the clock input A counter is a sequencial circuit with a set of flip flop which counts the number of pulses given at the clock input
Why when you put your indicators on your subaru sport rev counter pulses in time with indicator?
hi did you find out wat was wrong?
What is the mode of operation of IC555 timer in Automatic street light controller?
it is astable operation to produce clock pulses for the counter
What does it mean to have 2 pulses?
Having 2 pulses could mean that one is experiencing two distinct pulses in one location, indicating a possible underlying medical condition such as an arterial or venous abnormality. It is important to consult a healthcare provider for proper evaluation and diagnosis.
What type of radiation is best detected by a scintillation counter?
Gamma radiation is best detected by a scintillation counter due to its ability to interact with scintillation materials and produce light pulses that can be detected.
Digital tachometer working principle?
A digital Tachometer is digital device which measure the speed of a rotating object. A rotating object can be a ceiling fan ,it can be a car tyre etc. In this meter we just take no. of pulses for one minute then divide by 60,this gives the no. of pulses per min. And its reciprocal ie time for these pulses will be 60/N,where N are pulses for one minute. Then we apply these pulses(which in fact decide open gate time for counting the pulses of a clock signal). Now the no. of pulses of clock signal which are counted by a counter and divide by the open gate time(60/N) gives frquency of the of the rotating object. Since this frequency ie no. of pulses so this the original speed(rpm) of a rotating shaft.
What are the advantages of having lasers operating in femtosecond pulses?
The advantages of having lasers operate only in femtosecond pulses is that that is a very short burst. This means that there is minimal damage around the site that is being treated and the burst of laser light can be focused on the exact spot it is required.
What are the advantages of pulses?
pulses? like in the pulses you heart makes us hear?

Is there carbohydrate in pulses?
Yes, there is carbohydrate in pulses. .
What do you get from cereals and pulses?
From cereals - we get carbohydrates From pulses - we get protein
Where are the pulses grown in Pakistan?
Pulses are grown in 3 provinces of Pakistan. Punjab produces pulses at large quantity. Sindh and KPK also contribute in production of pulses.
