Suppose a recording is made of a piano performance. Lets call the analogue voltage coming out of the amplifier system as v(t) and it needs to be converted in digital signal. if v(t) is given as
v(t)=10*sin(2*pi*196*t)
do the following operations
Calculate The Average voltage generated in 6 turn full pitch coil of a 25 cycle alternator if the flux per pole is 7.2 x 10^5 maxwells. What is the effective voltage if the waveform is sinusoidal.
The sprinkler system is turned on ( set ON=1),if start = 1 The lawn is not fully watered and it is not raining. The output flow should be maximum when the lawn is too dry, medium when it is dry and drip when it is wet.
An amplifier with a power gain of 26 dB, is using a dual power supply of +/- 14 V. Find the peak-to-peak value of the largest input signal the amplifier can process without clipping.
Problem: A three-phase, 35kW, 400V, 50Hz induction motor operates at full-load with an efficiency of 87.5% and at a power factor of 0.8 lagging. Using the power triangle approach:
A sequential circuit receives decimal numbers encoded in BCD one digit (4 bits) at a time, starting with the least significant digit. The circuit outputs are the 10's complement of the input number, also encoded in BCD least significant digit first.
Investigate and produce a report on the main different logic families and their requirements - Describe with the use of circuit diagrams the difference between TTL (74 series) and CMOS (4000) integrated circuits.
Three single phase transformers rated 100kVA 13.2kV/2.4kV are connected in wye-delta on a 3-phase, 18kV line. Calculate the maximum load that can be connected to the transformer bank and the outgoing line voltage
What is the name given to the process of assigning a specific binary number to an instantaneous value on an analog signal
Identify and discuss an application in which an Edge-Triggered D Flip-Flop circuit is used and discuss why is it used, what are the benefits of using that circuit, in this application, can improvements be made in this application
Two loads are connected in parallel. The voltage across the loads is 8kVrms. The first load is rated at 12 kW with a 0.6 lagging power factor. The second load is rated at 20 kVA with a 0.8 lagging power factor. Find the complex power of the two lo..
Calculate the minimum value of Vd if the power flow through the converter is 5 kW (a) from the ac to the dc side and (b) from the dc to the ac side.
