摘要 |
A method of obtaining the peak value of a signal. The signal is sampled at certain intervals of time. The value of the sampled signal is compared subsequent to sampling with a value previously stored in a memory. The higher of the two compared values is stored in the memory for later comparison with a value obtained during a subsequent sampling. The higher of the values stored in the memory is stored in another memory after a maximum signal has been obtained.
