What are the disadvantages of asynchronous counter?

Counter circuits made from cascaded J-K flip-flops where each clock input receives its pulses from the output of the previous flip-flop invariably exhibit a ripple effect, where false output counts are generated between some steps of the count sequence. These types of counter circuits are called asynchronous counters, or ripple counters.


Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?

If the output power is 70% of the input power, then the output is roughly 1.55 dB downcompared to the input.If the voltage at any point of the output waveform is 70% of the voltage at the same pointon the input waveform, and the input and output impedance are equal, then the output is3.1 dB down (rounded) compared to the input.


How can IC 74190 will give output freq as 50Hz?

The 74190 is an up/down decade counter. Counters use frequency division to achieve a counting sequence. To answer your question, it depends on the input frequency. The Qa output will divide the clock input by 2 so if the input is 100Hz, Qa's output is 50Hz. Since this is a decade (0 to 9, or truncated sequence) counter and not a binary (0 to 15, or full sequence) counter, the outputs Qb, Qc and Qd divide the input but their outputs are not symmetrical (equal time high and time low). Qb and Qc produce 2 pulses for every 10 input pulses, therefore divide the input clock by 5. Qd produces one output pulse for every 10 input pulses, therefore divides the input by 10. The easiest way to visualize this is to write out the binary count in column format, starting at 0000 and ending at 1001, and looking at each of the output patterns. To produce the 50Hz output, assuming you are not concerned over symmetry: -input clock 100Hz for 50 Hz on Qa -input clock 250Hz for Qb or Qc output of 50Hz -input clock 500Hz for Qd output of 50Hz


What is the meaning of ctr div 16 on the 74ls163a?

In the context of the 74LS163A, "CTR DIV 16" refers to the counter's ability to divide the input clock frequency by 16. This means that for every 16 clock pulses applied to the counter, it will produce one output pulse. This division is useful for generating lower frequency signals from a higher frequency clock input, effectively enabling the design of various timing and control applications.


What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?

The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.

If input frequency of a full wave rectifier be n then uotput frequency would be?

The output frequency of a full wave rectifier will be twice the input frequency. This is because full wave rectifiers process both the positive and negative cycles of the input signal, effectively doubling the frequency in the output waveform.

Why PLL better than VCO?

A PLL is different than a VCO. Each has its own use. Actually a PLL (Phase Locked Loop) contains a VCO (Voltage controlled oscillator). A VCO is an oscillator whose frequency is related to an input voltage. You can use it when you need a varying frequency that is controlled by a varying voltage. But it is not great at outputting a consistant exact voltage because it is very sensitive to its environment (e.g. temperature). A PLL will "lock" its output frequency to some input frequency. So it can oscillate at a frequency that is controlled by an input oscillator. Not too useful if the output frequency is the same as the input. But the output frequency can be divided before it is compared to the input. This allows the output frequency to be higher (some multiple of) the input frequency. Once a PLL is "locked on" to an input frequency it can be very stable.


What effect does an amplifier have on the frequency of the signal?

A; An amplifier will have no effect on the input frequency however its output may not follow the input frequency at the hi end due to the amplifier limitations


What is meant by zero phase frequency?

The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.

What is the output frequency for a counter circuit that contains 12 flip-flops with an input clock frequency of 20.48 MHz?

12 flip-flops in series can divide by 4096. 20.48 MHz divided by 4096 is 5 KHz.Other division factors are possible, but 4096 is the maximum.


What is considered as the output and input terminal of the CB configaration?

In a Common Base (CB) configuration, the input terminal is the emitter, where the input signal is applied, and the output terminal is the collector, where the output signal is taken. The base terminal is common to both the input and output circuits, hence the name "common base." This configuration is known for providing high-frequency response and low input impedance.
