Description : What is the output frequency of an upper-sideband parametric-frequency converter?
Last Answer : The sum of the input frequency and the pump frequency.
Description : What are the functions of a converter-comparator group?
Last Answer : The comparator compares the signal strengths from the receivers and the converter converts the frequency-shift rf signal into a tty set dc loop control signal.
Description : What is the function of a converter?
Last Answer : Converts the audio signal to dc pulses.
Description : What is the discharge rate for the capacitor in a pcm converter?
Last Answer : It will discharge to one-half its value between pulses.
Description : Give the operation of single phase full wave bridge controlled converter with RL load with a neat diagram. Also draw its waveform.
Last Answer : Single phase fully control bridge converter with RL load: 1. During positive half cycle of input voltage, T1 and T2 are forward biased and during negative half cycle, T3 and T4 are forward biased. Therefore, T1-T2 ... cycle till the firing of next pair of SCRs as shown in the waveform.
Last Answer : A rotory converter can also be run as a synchronous motor.
Description : The decimal point of the base 10 number system is also known as the _____
Last Answer : Radix point
Description : An asynchronous counter is also called a ___________ counter.
Last Answer : Ripple
Description : You have just checked a 1/500-ampere fuse with an ohmmeter and find it is open. Checking the replacement fuse shows the replacement fuse is open also. Why would the replacement fuse indicate open?
Last Answer : The ohmmeter causes more than 1/500 ampere through the fuse when you check the fuse, thus it opens the fuse.
