The Canaries were left unsuccessful in their attempts to bring in Celtic's Gary Hooper and Sporting Lisbon's Ricky van Wolfswinkel but Hughton did improve his attacking options with the signings of Luciano Becchio from Leeds and Kei Kamara on loan from Kansas City.
Kamara made an impressive cameo appearance in Saturday's 0-0 draw with Fulham and Hughton believes that the new signings can fire his side to safety.
He said: "This season for us was always going to be a difficult one after last season, but if we can keep chiselling away and, looking at the players who have come in, generally I've been delighted with them.
"I don't like to go back to before I was here, but I think that's been the case every summer over the last three seasons, where there have been a fair amount of additions to the club and, of course, the purpose of that is to try to keep improving the squad."
Hughton is also confident that Kamara will bring something new, saying: "I hope so. He is different to what we've got. Becchio is somebody who needs service in and around the box. We all know what Grant (Holt) gives us inside and outside the box.
"Simeon (Jackson) is a smaller, brighter player that has a little bit of pace and Kamara is one who has that bit of pace as well and he's very, very good in the air but he can also play in a wide position so he gives us a good option right across the front."
The Norwich squad are currently enjoying a break in Abu Dhabi but Hughton insists that his team will be fully committed when Everton visit Carrow Road a week on Sunday.
He said: "How are we going to come out against Everton? I know we're going to have a group of players who will try very, very hard.
"But it is always a difficult thing (after a break). In our game you don't know. You hope we come out firing and playing fantastic football, but these are the things you have to keep working on, week in, week out."
He continued: "If things are not right after one performance you have to strive to make it better for the next one and the next one after that.
"These type of games are maybe slightly different when you come up against the real good sides, but I don't think it is necessarily true to say we seem to raise it even though we have done well against the likes of Arsenal, (Manchester) United or Tottenham."
